Does Simon have a site for his S8 ECU anymore?

I'm after a copy of the software and I'm sure you used to be able to download it from there?

 

http://www.s8ecu.co.uk/


Not up at the moment though mate.


I wish he would "pre release" the windows software but on the other hand i guess he really cant until he knows that its been tested properly.

annoying when you are waiting for a copy though!

 

Awww bugger. Can anyone sort me out with a copy Chiiiiiiiip Pleaaase

 

I havent got the windows stuff myself yet mate.

 

Not after the windows stuff. Just the old software.

How big is are the files?

 

I can email you the software mate, but im not near that pc till the weekend now as im in london and its in somerset.

 

Just spoke to simon on the phone. Answered after 3 rings!!!!

Don't know what you guys are all complaining about!!!

He said website should be back up in new re vamped form in a couple of days!

 

Cheers Chip,

If the website isn't up by then i will drop you a PM.

 

Ok mate

 

Garage19
give me your email addy and i'll sort you out. sold my S8 at the weekend to a member off here and burnt him a cd with all software that i have so far, so have it all handy

 

"all the software?"

sounds interesting, can you bring a copy to the berks meet on wednesday for me in case you have anything i dont?

 

Thanks Nick... you are a star.

I have PM'ed you my email addresses.

Out of interest, why did you sell you S8?

Did you ever have a play yourself. What did you think of the software?

Cheers,

Doug

 

Hi M8

I am the guy he sold the ECU to! Nick is a most helpful guy. The windows version I have had a quick play with, and to be honest, it isnt quite there yet.

The original dos version still works as it should do though. If you have a broadband account, I will email it to you.

I am currently on the search for a map for mine though! I managed to get the S8 to run the old girl, but it wont idle. Dont have a clue why, and am massively out of my depth!!

Oh well, got to have fun!!

Cheers

JJ

 

JJ you have PM.

What car are you trying to run the S8 on? Cossie?

 

Hi m8

You now have mail!

I am running on a 2WD Sapph cosworth, on stage three (greens with 3 bar map sensor). Other mods include T35 turbo, and the like. The rest is rebuilt strong, but to standard compression.

Hope I have missed something dumb!

Cheers

JJ

 

Garage19 you have email. could not be delivered to your work address as it contains .exe and .zip files sold it as i need the money for a house deposit. simple as that really. had a little play with it, but nothing much. thought it was good, but never had a chance to have a proper go at mapping as i am a billy no mates so have no one to do the driving.

chip-3door will do


JjCoDeX75 you'll learn, just play about a bit. glad that the windows version worked for you

 

Hi foreigneRS

Got the bugger to run, now all I need to do is get it to idle!!!

The map that seemed to be best so far was yours - the one originally called estate!

Modified the TPS setting, and car would run, just not idle, and a little unwilling to start.

Hah!

Back to drawing board!

JJ

 

hi JjCoDeX75

strange really. it would start my engine from cold or hot no problem.

is your fuel pressure correct?

have you calibrated the sensors (especially the MAP to give a zero reading when engine off)? think it's called sensor trim or something?

compare the original 4803 map with the 'estate' map and see if there is a difference in injector duration in one way or another. if there is, maybe increase it in that direction if the 'estate' map runs a little better.

get a wb lambda sensor really, otherwise you're pissing in the wind a bit

 

HI Nick

Hoorah - managed to sort it!!

It seems that the settings on both for the idle control valve were seriously upsetting mine. The ICV was basically refusing to adjust the idle, and as such, it was attempting to idle at 600rpm!

I grabbed the idle control settings from the standard yellows map, and superimposed this into the estate map. and we got somewhere.

Then, had to sort the advance. On the estate map, the BTDC was way too advanced for my car (at approx 32 is on idle settings in the map table). I adjusted these back to approx 16 BTDC, and also adjusted the fuelling upwards, and hey presto! The car will now idle on the S8.

With that now settled, I will now need to set aside a SERIOUS amount of time with my mates wide band lambda and rolling road, to get a complete map!!!

All fun!

Did you ever work out how to interface your Tech Edge Lambda sensor with the S8, or did you not get that far? And also, what was the name of the manufacturer for wide band controllers did you recommend (I have the memory of a sieve !!!!!!)

CheeRS

JJ

 

sounds good JJ

i did interface the techedge to the S8. piece of piss, just one wire from the simulated narrow band output of the wb controller to pin 2 of the S8.

with the original software version, it will only take a nb input. later versions were going to take a 0 - 5V wb output, but don't know if that was implemented on any of the updated versions that i left with you.

i would recomend the techedge again, but with the bosch sensor rather than the NTK one. the bosch is much cheaper, so you are more inclined to replace it when it gets a bit dirty and the response slows down.

as i said though, the datalogging software for TE is not great, and looks better on others that i have seen like Innovate, Zeitronix or Dynojet

see these other threads for more info.

Cheers Nick!

You are a source of much useful info!

The 0-5v input is what I have been told to look for, but I can unfortunately see no evidence of this in the current version. Hopefully Simon will release an update soon that will allow this input to be added!

Just for final clarity, I read through the manual, and have managed to pinpoint the EXACT setting that was preventing my car from running.

In the idle control screen on the setup, the bottom input box (which I cant remember the name of) is an override. Any figure in this box will override the normal control of the idle control valve, unless this figure is set to 0. In the estate map, and the base 4803 map, this figure was set to 1%,and as such the Idle Control Valve was doing nothing at all - hence no idle!

I'm not sure how it managed to idle on yours at 1000rpm with that setting!!! Doh!

Probably no point in worrying, but if you are bored, unplug your ICV lead whilst the car is running, and seeing what it idles at naturally...

Nick and JJ - cheers chaps. Software got through on one address ok.

Software seems pretty easy to use, once you have got used to function keys and esc to do everything. Its slowly becoming more natural.

Haven't tried the windows based version yet, but i am sure it will be a big improvement.

Thanks again guys. I will let you know how i get on.

 

Further on from my request for the software.... I don't suppose any body has a pin out diagram/list for the loom connector??

Sorry for being a pain in the ass.

 

Garage19,

I think that one of the text files gives you an indication as to what each pin does, but dont quote me.

A lot of them are the same as the ECU that you are using. I have at home a complete wiring diagram for a L1 and a L8 ECU, which will give you all the positions.

If you still need by tonight, I will email to you when I get home

Cheers

JJ

 

correct - text file CONNECT gives pin information

copied and pasted from there, but could turn out a bit wonky due to bb code

Ta muchly

 

I wouldnt recomend using the simulated wideband output personally on the techedge, by defualt its at 14.9 which i feel is a little lean, also it means that as the wideband sensor goes out of calibration you dont know, but if you have a seperate narrow band sensor it becomes VERY obvious when its out of calibration as it starts looking like the closed loop is at the wrong value.

So i prefer two sensors, and a narrow band sensor is pence secondhand anyway.

 

good point chip

as you say 14.9 as standard, but it can be re-programmed

 

Its a hardware change to alter it on the early models.
Although not an especially taxing one.

 

I must admit, I like the idea of redundancy in having two sensors.

It also strikes me that the SECS could do more with info such as knock and EGT. I see inputs for both on the ECU, but havent found a way to override or adust settings in the event of fault.

I wish my programming was waaay better than it is right now!

JJ

 

My programming is good enough to do all the things that are needed on the SECS, (i used to write realtime control software for ECU's anyway) but sadly i dont have the source code, and obviously im never going to have it either as Simon would be a fool to publish it!

 

Doh!

that is a shame, as I get the feeling that the hardware has huge potential beyond the softwares current capabilities.

Hope Simon doesnt see this as a critisism; what he has done to date is fantastic.

But a good thing could be great!

JJ

 

Its a work in progress still essentially.
