please help.

whats the difference between the

l6
l8
p8

and are the interchangable. can u swap them with each other.

if not, what needs changing?

 

If you mean can you just fit a different ECU to the current loom, then yes you can. However, the EPROMs are not interchangeable and the 4x4 cars run a different throttle position sensor that would also require changing if a "non" 4x4 ECU was fitted and vice versa if fitted to a 2wd car.

 

also the outer wires of the tps will need to be swapped

 

i want 2 change a l6 and replace it with a p8

is it worth it?

whats +'s?

 

And the level 8 and P8 can run lambda and knock control.

 

P8 can run ALS, distributerless and closed loop boost / lamda control.

 

thanx to all for advice. Sounds like its a much better ecu than what i've got.

 

can any please give me any more details in terms of effect on my engine this ecu will have.

I am running greens and 3 bar at the mo.

Gona be getting a t34 with .63 rear housing, and may change the cams. Still waiting for the review on the intercoolers.

Will it run better with a p8 than a l6. boast kick in. Mapping capability is it better?

 

If you car has already been live mapped, it is unlikely you will notice much difference.

 

no its not been live mapped. but will be. either stu or karl i hope.

I just want to get everything perfect before phoning them up and wasting there time.

 

if you dont want any of the toys which p8 can offer (als, knock control, closed loop lambda) then it isnt really worth paying the extra for it

 

Mike. Could there be any problem running a 4x4 Ecu on a 2wd engine. I mean, could that of caused any problems in my car due to the TPS being defferent? (mine is a 2wd engine with..I think..an L8) Or am I being a t*at as usual

 

if you mean that you was running a 2wd tsp, they your fueling would of been all over the place

 

yeah, you wanna watch out when running teaspoons instead of TPS's. the fuelling will be all over the place.

 

Gareth! how can you put a after saying that pmsl.

probably got something to do with why my engine went night night

A P8 is from an RS500 right? so the TPS would be the same as my 2wd one?

 

 

Dom,
I doubt this was responsible, it was you holding it flat out when it was not checked out However, worth a check - TF01 is 2wd and PF09 is 4x4...

 

Dom,
L1 / L6 = 2wd TPS

L8 / P8 = 4x4 TPS

 

cheers mike , tosser I'll have a look later

o, by the way. That turbo I bought.....its fucked. Dunno how I didnt notice it there. I checked it well, from one side but didnt do it properly obviously

The play is so bad the blades can hit the compressor housing

1200 quid for a bedroom ornament

 

Dom,
Is this up and down play or side to side? . Up and down is okay, as the shaft sits in a bath of oil when the engine is started, so it needs this freedom of movement, side to side is nicht gut .

If it really is fooked, I'm sure Danny will sort you out, he's a good old stick .

 

If you were still running the 2wd TPS with the level 8 ecu then at WOT you'd have no WOT multiplier working. Not all mapping uses a WOT multipler, but most do, and typically it is in the region of 10 - 20%. If your chip was mapped as such then at WOT you were likely running 10 - 20% lean. (since your 2wd tps was giving the inverse signal of the 4X4 )

You should have noticed the incorrect TPS though as your idle speed contorl valve would have been inoperative, and at cold start would have been very apparent that the car started badly.

 

Mike Rainbird, erm, im not sure. ill have to check. It is bad though...I will have to check whether its side to side or up and down. He seemed like I top lad.I have PM'd him. But as he needs the money at the mo and he is not a trader then I could see him not wanting anything to do with it.

Karl, Cheers mate. interesting. I was using an A1 rallysport chip, it wasnt live mapped (Mike )
I think it could have been an important factor in my engine going kaboooooom

funny because I actually read about this TPS before I blew it up and worried about it for a couple of hours until I forgot about it. lol

 

A P8 is from an RS500 right? so the TPS would be the same as my 2wd one?[/quote]

No. A P8 is from a large turbo escort cossie

 

maybe i am thick, but wot is closed looped lambda and boost control. Obviously i know what boost and lambda are but what does the closed loop bit mean.

cheers

cheers

 

The ECU uses it's sensor readings to set it's own boost and fueling accordingly....not sure if it controls anything else...

 

Hi, this maybe a dumb question, new to cossies, but is there software available for mapping the L6 ECU (RS500) I doubt anyone here in Aus would have it, we have a dyno and map Autronic, Motec and unichip, would like to knw how to get inside the 500's brain, any advice greatly appreciated

regards Paul B

 

Paul,
Yes, Simon at SECS has developed a software package that can live map L6.

Thanks very much Mike, no answer on his phone (from web site) but I'll keep trying, have you had experience with his systems, or know Simon and how good the system would be ?

regards Paul B

PS the conversion to knock, lambda L8 etc a hard one ? worth it if tuning ourselves ?

 

Yes, Simon can be a bit hard to get in touch with sometimes, but the set up works, as a well known (in this country) tuner uses this set up for live mapping L6.

I don't think you can beat a set of det cans, so would always rely on these rather than some for of electronic detection of knock.

The conversion to L8 and lamda is simple enough using the OE parts. Obviously the fuel economy / emissions can be improved, but depends if this is important. You could chat to Stu at MSD about this side of things, as he has stepped up the development of these in the last few weeks.

 

Im gonna put the p8 in and change the tps.

I think that should do it. Is there anything else i need to do?

or change

jrst

 

Mike, thanks very much for your help, I'll try to get in touch with Stu and Simon.

JRST, appologies for partly hijacking your thread, still along the same lines enough I hope, best regs pb

 

elxr8393,

you do need an emulator if you wanna map cossie ecu's live

 

no probs mate. At the end of the day we are kinda talking about the same thing.

Wish someone would just tell me though whats needed to convert to a p8.

sometimes its hard to get a straight answer.

Please help.

Thanx to everyone who replied though

 

Thanks, so I guess we are talking about the same thing - converting to L8 and not knowing exactly how, and some new info for me there - the emulator, could you please explain that, is it in addition to Simon's invention ? thanks. pb

 

Ahem:
Funny you should say that.....

stu can u help mate. can u let me know what i need to change on my 2wd saph to use my p8.

sensors?
wiring?

please, pretty please

 

TPS = PFO9

swap top and bottom wires over on TPS plug.

If required add a lambda sensor and Knock sensor.

IF using Pectel software, dont add these as it wont utilise them.
I recomend they are retained.

 

stu u are great.

thanx for all your help.
