looked good andrew good to meet ya again as always had a good laugh too,see ya next month bye all accounts maybe nick will bring the car next time take us a blast.
Maybe a race lol

Rick

Andrew - thanks for your reply. This ecu is proving very interesting.

I'm a little puzzled as to your comments on cylinder filling. Just because the car has an increase in manifold pressure over a NA car, this doesnt change the filling characteristics. I can acheive 10psi of boost on very light throttle loads, where the cylinders are still only being partly filled, and the car isnt accelerating particularly quickly. Plant the throttle, and still limit the boost to 10psi and the car will go like hell - as its now breathing far deeper.

How does the ECU deal with transient fuelling? Are there algorithms in place, and can these be adjuted?

Also, what kind of connectors come with the ecu? What are the practical aspects of making new connections to it?

Rick.

Maybe you should seek more infomation on the cyl filling under boost - I'm no expert on this but am just putting forward what I had been told, regarding ignition and boost.

Maybe you are correct - but that matters not. The answer to the question is - you can get accurate mapping with only a map sensor, and this has been proven with many turbo and s/charged cars running Gotech - Supercharged 6cyl BMW's - Nissan/Toyota Turbo motors - Rotary turbocharged RX7 - Alfa V6 twin turbo - Ford V8 and V6 ect.

The AFR curves for Nicks RS turbo are nice and smooth for transient fuelling, and during full power runs, and cruising - we have 32 load points to play with from -1 to +1.5 bar. DTA P8/Emerald/Omex have only 20. How many load points are user adjustable with the Cossie management conversions as I'm not sure?? I've heard they are good at low revs but higher up you can only map in large chunks. (no experience with this system - only curious)

I'm sure you can get better with Ł3000 of motec, but hey, we're talking a much more affordable solution here. Any of the RS Turbo's running CVH ke-jet/Zetech turbo's, respond extremely well when running Gotech.

Gotech can map with MAP sensor input, TPS input, 50/50% mix of map & TPS, or TPS on vaccum until positive boost is sensed, then it switches to MAP senor. The last setting is particularly nice if you run throttle bodies and turbo - or wild cams and turbo, where the idle vaccum is low.

omex/dta/emerald/pectel-T2/haltech I believe dont offer this feature (correct me if wrong please)

Gotech looms use amp connectors, and the looms are fully finished for your application.

What new connections would you require?? Let me know.

What engine management system are you currently running yourself??

Lets not turn this into techno overkill - I'm just letting the RS turbo/zetec/pinto/cossie owner know there is an AFFORDABLE new system available, that is a quality product.

Thanks again


Andrew

You can also ask JamSport!!

I haven't read all of this, so I may have missed the point.

I have seen references (in the title) to 'Gotech MFi', then references to losing the Metering Head and fitting other Injectors.

What part of this concept relates to MFi? The 'M' of MFi refers to the Mechanical aspect of the KE-Jet system, does it not?

Someone set me straight?

Gotech Racing

Gotech MFI-STD is a standalone engine management system - the 'M' of 'MFI' is just part of the product name.

References to losing the metering head were in regards to what is replaced when fitted.

The 'fitting other injectors' was in regards to using Gotech MFI-STD in a 5th injector control only situation, then upgrading to full fuel and ignition at a later date, for the budget user! As the price compares well to the 5th injector kits currently on the market.

Start at the top!!

Thanks for the interest

A few of us on here like the techno talk!

mark-rst

Does the ecu control the Amal valve as well?

DazC

iTrader: (1)

Even better, will it control air to air injectors?

Gotech Racing

Hi Mark-rst

No control for the AMAL valve. We have found these type of valves give lots of trouble when the boost is increased.

We prefer the adjustable 'gated boost valve'. the Turbosmart type has given great results!

Thanks

Andrew

Gotech Racing

Yes, It would be nice - but the MFI-STD has no air injector control.....

Prototypes in development will/mayl have this facility. But on a more expensive model.

For the power you're restricted to through the front wheels, there can't be many cases where it would be essential to fit?!?!

Gotech offer the great advantages of engine management, at an affordable price! Air injectors or not, it's a great piece of kit!

Andrew

Will it bring me breakfast in bed? Cos my mate Dave who skimmed .050 thou off his fsie's head and made it beat Ferrari's said his WafflaloadabolX
Digital defruiter system does/if properly mapped obviously........................

DazC

I just see the air to air as a means to accurately control and maintain the boost with closed loop boost control, and maybe an adustable boost pot for different levels of boost. Even without the closed loop, the boost level can be mapped to give a characteristic to the boost curve or to hold it stable if a boost spike isn't desired.

I agree there will be very few applications that air to air are NEEDED but I think these or a good boost controler are the way forwards. I prefer mapped in air to air with a good LOS.

Gotech Racing

Agreed! Yes air to air will give accurate boost control.


Gotech may feature this in future models.

But for the majority, Gotech MFI-STD will do the job very niclely, and wallet friendly!

If you really need air injectors go to motec/autronic/pectel systems ŁŁŁŁ!

What do you run on your car - cossie system with air/air??

DazC

iTrader: (1)

I am still surrently runnin the KE-Shitronic system.

I have my ECU and loom awaiting fitment but I don't currently have all the items required for a full management swap. Until I colate all the parts (sensors and injectors), I will remain on KE for now. Included in the parts I have sat here waiting is a single air to air and a double air to air set up. I will be using the double air to ait and the single will eventually be sold on.

Gotech Racing

What ecu do you run??

How much have the parts/machining/mapping/fitting cost?

DazC

iTrader: (1)

I am not going into what spec I have opted for as currently very very few people know about it.

However, not as cheap as your Ecu I will say that much! You did mention the manufacturer earlier.

I am fitting all new parts including new fuel pump, filters, fuel lines, pressure regulator, modifying the manifold to suit a fuel rail and EFI injectors, new sensors and injectors.

Gotech Racing

Sounds NICE!

turbotoaster

hi, just wondering is it only jamsport who will fit this as im interested in fitting it to my renault 5 turbo, but with jamsport being ford guys i dont know if they would touch it, if not does anybody know of any tuners who would have a go at this

Gotech Racing

Hi Turbotoaster

Yes. Jamsport are the Gotech main dealer in the UK.

Gotech will work well with your R5 turbo - you can go full management fuel and ignition, or if you keep the carby, go to fully mapped ignition control.

You can even just use as a 5th injector if you like!!

JamSport aren't just FORD guy's, and I'm sure they have worked on R5's before.

In fact they have just finished a Gotech MFI-PRO install on a Vauxhall Corsa on Jenvey throttle bodies, wild cams etc. Fitted and fully mapped in house, results were fantastic.

Thanks for the interest

JAMSPORT

Hi Turbotoaster

we have had lots to do with R5 GTTover the years with good results.

i do lots of tuning work on the rolling road,setiing up 5s for a tuning company that only dose 5s and it was only just today that we where looking at fitting gotech on this actual car because it was on its limit @245bhp.

we are going to fit a 5th injector and also a tps so that we can map the fuel and ignition which has not ever been possible on 5s befor with a carb.

with doing this it will get rid of the over fueling at low reves and the under fueling at higher reves which is allways tippical on high power 5s.

this will in turn give you more peek power and more importantley lots more lower down torque as it is the power under the cuve that will make a fast car.

gotech will still give you the option at a later date to go full efi if you wish this.

Gotech Racing

Rick:

What engine management system are you currently running/mapping yourself??

And how does this map the transient fuel & ign??

All:

We will have an Escort RSTurbo at the thrash, running GOTECH MFI-STD, available for demo.

So everyone can see the ECU first hand, feel how smooth ths car is, and check out the software - and the fantastic DATALOGGING.


Thanks again

Hi Andrew

I currently have the STD KE coupled with an MF2 fifth injector.

The fuelling i couldnt ask to be better. The fuel pressure has been reduced so that the car runs around 15:1 off boost. When on boost, at low it's around 12.5:1 then going to mid 11's under full load.

By it's very nature, KE is very good at dealing with transients so driveability is very very good.

The probems im experiencing are to do with ignition control. My chip in the ESCII module is mapped to 22psi, but there are few load/rpm points, so after 22psi, it flat lines.

Need something to control the ignition.

Rick.

tubbykev

been in contact with jamsport this week regarding the gotech engine management and must say im very impressed with the value for money factors and its capabiltys. Im seriously considering this as an alternative as it would free up some funds for extra mods which was gonna be going towards omex engine management.........hopefully coming soon with new turbo and -34 actuator

Gotech Racing

Ah okay with you.

So you've not worked with engine management as such.

How many load points/break points can the 5th injector be mapped?? Is it based on map sensor or rpm? Just curious...

Where you do loose out with the KE jet, is the restriction of airflow as a result of the metering head, especially off boost.

I have no doubt that the fuelling is very good, and gives good drivability!!

Running Gotech on the RSTurbo really transforms the drivability...... you are able to run much finer ignition settings, which give a really crisp throttle response (even off boost) and the low and mid range power is given a nice lift as a result.

I can see how you're now going to struggle with the ignition side of things......

Have you considered full management before??

Gotech Racing

Nice one tubbykev!

Wait 'till you start playing with the launch control

Maybe you can keep us posted on the progress if you go with Gotech on the forum??

Nicks car will be available for demo at the PF thrash, so hopefully you might get some first hand feedback on here....

Tim

iTrader: (1)

Gonna ask nick to take us a blast so i will report back lol

Rick

Yes i have. Lots of differnt systems, i mainly deal in v low gate level stuff though lol.

The reason im still on KE is becasue my car is the daily driver, and i cant afford to take it off the road. Otherwise Efi would be on along time ago. I also cant justify the expense, of all new sensors, looms, etc.

The gotech system is intetesting, as it would be a simple ish job to take the timing from the dizzy, and use the ECU to control the ignition. Once that is reliable, i could use it for fuel

Rick.[/quote]

Rick

The MF2 has 9 interpolated break points, which for fuel is easily enough. Engines are quite tolerant to a wide band of AFR's, unlike ignition advance! It has inputs for MAP and RPM, it really does work very well.

Gotech Racing

Okay, cool

Which systems and what model cars/ engine types.

What were your mapping results....? were you mapping for friends or one of your own motors.

Did you map for ignition advance under load? Do you have access to a testing ground. I guess you've got w/b lambda gear - which type? innovate/WBo2 tech edge/motec or many of the others available.


Hey! are you coming to the thrash?,

If you are I'll look forward to meeting you

Regards

Gotech Racing

Hi Tim,

Looking forward to seeing you guys, also your feature looks the bo***cks if i say so myself

Jamie will be demo'ing the RS turbo, and I'll make sure you get plenty of time with the car - can't wait to show you the datalogging

I think your car will do pretty good on the day mate

See you there


Andrew

Oranoco

Can't arsed to read all the posts but why do you want to change. The OFAB management is very capable indeed and is easy to convert to if like me you are on OFAC. Mate used OFAB management on his 2.1 Zetec turbo until recently and achieved 316bhp

Gotech Racing

Oranoco

What RS Turbo's use OFAC or OFAB??

Were you replying to a specific post?? Or did you post in the wrong thead.

Regards


Andrew

Oranoco

H196jne who posted the topic drives a Fiesta RS Turbo. These come with Ford's own OFAB or OFAC management systems which is an EFi system as opposed to the Escort RS Turbo's KE-Jetronic system which is more mechanical.

I assumed the post was about his own FRST hence my post.

Unless I missed something which isn't impossible as I'm not fully awake yet

Gotech Racing

Yes, your right!!! that was soooo long ago i'd forgotten

must be more asleep than you

Thought the pics would come out nice was a cool day,was happy with the times tbh , maybe a bit more topspeed this time found a few problems that didnt help lol. But the sprints were awsome hope to do similar again.
Be good for a blast in nicks car anyways see how it drives compared to cossie stuff

Cya then.

Mr RS

can you run anti-lag on this management?
