I'm no expert but i should imagine to map ignition for off boost you would just hold a specific load/speed site and then advance/retard the ignition timing until you achieved the best torque reading?????
I should imagine that mapping ignition on high load sites is where the real skill/experience is needed???
Any tips stu? Do det cans make it possible or is it mostly down to experience?

First This is probably one of the best topics here on this forum.
On some us ford forums they are tweeking the original eec iv ecu of the mustang, and I think they are fitting bigger injectors and even one odd supercharger. Is this a different ecu from whats in the late model Escort?
When your are mapping ignition of boost, are you then mapping for best torque?
I think you said sometime that adding ignition after best tourqe may result in less? Or something similar.
And a more basic question What is a det can? I think some kind of knock sensing equipment, but not sure.
The KnockLink, or whatever the link knocksensor is named, is it any good??

I can't just get to that if anybody can make my Escos nice 300-330HP with nice torque curve on EEC IV. Anyway I'm going to test chip for it by Stu soon and maybe that will be enough.
I wonder if it's mine or Stu's communication skills that make us unable to comunicate about that :-/ Probably just my poor english.

But from what he says on this thread it seams he can actually Live Map EEC IV..... then I have no idea why I couldn't fit small GT series and do about 330HP from EEC IV. EVEn if MAF/MAP maxes out at the top end or fuel pressure would have to be slightly upped.

We already know that an standard Marrelli L8 ECU will run 750cc injectors with brilliant emissions and drivability so standard Marrelli P8 will also control 750cc as the L8, will but to my knowledge 1000cc injectors has not been tried YET.

Stg 1 on EEC IV Escos is quite distant from stock engine. Depending on tuner it's around 300HP and almost twice the stock boost! Stg 1 YBP Escos is by now means a slow car, here in Poland I haven't met faster on track or road yet exept for just one Scooby.
Anyway I schould probably just leave the engine alone for the time being, untill I have funds for complete rebuild + Autronic, IC, turbo, waterinjection and lots,lots of stuff.

I know I know - I mean that if live mapping is possible, then even if we are limited by EEC IV sensors and actuators we can still make some improvements - fre exhaust and intake, head porting/polishing, the same with manifolds, uprated hybrid turbo with ported/polished insides, all this can be used to full extent if we live map it.
I know it's kind of stupid compered to the power one could get from old YBT with this sort of work but still it may be interesting option if e.g. I have to rebuild engine if future because of wear I could do those things as byproduct.

Azrael,
But inside limitations of existing sensors it is doable no problems? Injectors I think last until about 300HP?
But inside limitations of existing sensors it is doable no problems? Injectors I think last until about 300HP?
The standard airmass meter is also on its knees around 300bhp, not just the injectors We can increase the fuel pressure no problem and make a custom map to take us to the realistic 300area but i still would need to spend a good few hundred hours with the system to find the injector scalar maps and other associated maps such as cold running and air mass to make larger injectors work "properly" should we want to go any higher, and this doesnt get round the fact we are on a wing and a prayer with an air mass meter wide open, so would need to look also at fitting a bigger more capable unit. This then opens up a whole new can of worms as the airmass scaling within the control maps is totally bolloxed, leading to more R&D to get this lot working again... In Short, its arguable wether the few people willing to pay the price would offset the time and money required to make this workable. I far prefer the idea of plugging in a SECS ECU and the fooker just needs maping.
I hope that addressed your later comments too, but if not, please ask.

Ive no idea. Im pretty sure i could get your std P8 hardware to do it... But no idea if your 8inj hardware will do it. Maybe give Harvey/Ahmed a shout

I use a fuel monitor that can display oxygen values as well, so i can map to teh point of oxygen content appearing in teh waste gas. This will indictae a missfire before i can feel one.
Other than running problems, we map to detonation and then back, but in all honesty, experience gives better results than det cans off load as a low comp motor will swallow up advance and just run crap, effecting driveability and emissions terribly.. thats a fact.
We also map with our G-Meter at times so we can measure constant G. This is a good way to gauge improvements in torque whilst mapping live.

Our system goes one step further:
Its a set of electronic headphones with 4 seperate microphones and a 4channel swicthbox so i can listen to different areas of teh engine if im in doubt as to what im hearing on one sensor.
You can see the sensors hooked up in this pic:
And the cans and switchbox are just visible on teh dash in this pic:
Knocklink etc are quite usefull once youve got them set for the engine its supposed to monitor, but ive found it next to useless for transferring from car to car, as its so hard to setup

hi stu
i had a lot of questions regarding ignition maps on the last page. i'll repeat them and break them up a bit to make it easier (although you have mostly answered some of them ).

1) what tools do we need (for example det cans, knock sensors, EGT probes, accelerometers etc) to be able to setup the ignition maps well?
2) and what are we looking to do in all areas of the maps?
a) for example on max boost we want to advance for power but not too much for det,
b) but what about coming on boost (where we may want to run not as much advance for higher egt temps to give energy to the turbo for faster spool up, for example),
c) around idle,
d) below idle (big advance to get speed up again?),
e) cruising,
f) gentle acceleration,
g)off throttle (cut ignition and fuel?).
many questions in there Stu, but we'd appreciate your experience and teaching as much as possible (and any other tuners, pro or diy)

Now I'm getting to understand whole thing.
I far prefer Plugging in S8 ECU but I can't see it becoming avalible for EEC IV cars in forseeable future and becoming tested and reliable unit :-(
Still I watch very closely effects my friend has hre with his T4/greys Escos and S8 ECU which a tuner here in Poland is trying to map for him. So far It runs very quickly but still have too little HP and has BIG trouble with cold starting. It was fist some hardware issue which was I hear adressed by SImon but now I think it's jus a problem of learning to map a thing.
By the way Stu how do you think -> if someone can map 600HP Supras and group A Escorts with Motec/GEMS can such a pesron map S8 ECU or some other exotic product like Pectel which is unknown here? I mean is tis skil very hardware dependent?
#312
1) what tools do we need (for example det cans, knock sensors, EGT probes, accelerometers etc) to be able to setup the ignition maps well?
Good Laptop with long battery life.
16bit Emulator with 35ns max data speed and at least 8mb internal memory. (To run 2x 4mb roms at once)
Battery backup system for emulator that is capable of storing the run map and feeding the ecu with this rom for 1hour solid to get you home should the laptop or emulator fail out in service.
(Remember, your ecu has no chip in it )
Wideband fuel monitor that ideally shows both Fuel AND Oxygen.
Its nice also to have both AFR and Lambda displayed.
Knock cans of some form, to enable you to hear engine noise from within the cockpit.
Accurate boost gauge for forced induction engines.
EGT monitoring is very usefull on Turbocharged cars.
G-Meter is usefull but not strictly a necessity.
A mobile phone to call RAC
2) and what are we looking to do in all areas of the maps?
As for spark, we need to be advancing to either peak torque, knock, or oxygen input, whatever comes first and then back to adetermined safe level back away from this peak. Again, i have my own feelings on whats safe to retard back to and its not for public consumption. Sorry
Next...

1) Youve obviously invested heavily in hardware to support that turbo's potential airflow/horsepower and dont want to lose your investment due to a failure of an old ecu. (These units arent the most reliable as im sure you know already)
2) You would be well advised to utilise things such as EGT fuel control with that unit and a whole host of other great safety features that the aftermarket ecu will give you such as injector failure control.
3) The time spent diagnosing problems in teh future can be cut down massively with a decent aftermarket ecu.
Hope this helps.

Incidentally...
We did a Pectel T6 2000 topic that showed all teh configuration screens and counted around 800 adjustable maps and options.... may be of interest to folks who are interested in mapping...

thanks a lot stu. i can understand your position about AFR's and ignition timing 'secrets', but it's very frustrating when you tease us by getting us to ask questions that you know you won't answer.
the practical basics of mapping are relatively simple (especially with aftermarket ecu's with user friendly gui's) but it's the details, that i suppose are only gained through experience, that make the difference.

Foreigner RS - to learn to map properly one must probably explode a number of engines over the years to gaing experience. That's why I'm not very fond of doing any big HP here in Poland as basicallynoody had possiblity to blow up some Cosworth engines. Dunno if I am right but this kind of expensive experience may be invaluable.

If I win a lottery or something I will be looking for somebody in UK whom I can leave my car for few months and get itback with everything done from engine to missing clips in interior

I know they had a lot of problems with basic setting on S8 ECU to get engine runnning, and still there aresome problems with the way it operated ISCV and cold start.

Azrael, The problems your "friend" is experiencing are down to
mapping and nothing else.
I have responded to all emails and questions from him and step by step
he is sorting out the problems with his map.
ECU's ARE complicated products and the S8 is much simplified when compared
with others but still require a level of skill, understanding and experience
when setting them up.
It is unfair of you to blame me for "others" inability to understand how to map
and configure an ecu or failure to understand how engines actually work.
If it was that easy Stu and other tuners would be out of a job.
At the end of the day, no matter who's ecu you use or no matter how much it
costs, it will ONLY be as good as the person tuning it and also how much
time and effort someone is prepared to put in to it.
Most people only think about the full load power mapping but there
are many other parameters needed for example cold start etc...
For your info, the S8 EEC4 plug and play version is actually nearly ready for sale.
It is not available yet due to it being tested in the real world at present
by a WELL KNOWN respected tuning company.
Once they and I am happy with its performance it will be sold - not until then.
It is a shame that not everyone understands the amount of work that actually goes
into a product like these in terms of development.
It is NOT a five minute job.
