Afternoon,
I have a standard 2wd saph and was wondering if anyone could tell me what i would need to change on the car to upgrade to a L8 ecu.
I know i need to change the TPS outer two wires round and thats about it.

Any info would be much appreciated.

 

TPS, Knock sensor and Oxygen sensor if needed.
Wiring diagrams here: http://www.bigturbo.co.uk/main6.htm

 

What he says^^^, if sticking with L8.

Is it worth doing to a standard car?

 

If you don't need things like Closed loop control, launch control or ALS, then stick with what you have.

 

At which point do i want to change to l8? goin for 400+ but not interested in closed loop, als and launch.

Is knock sensor and oxygen sensor needed? Thought i just had to invert the cables to the TPS.

 

dont bother.... just go to a T2 .... very nice piece of kit!

 

you dont need these on the earlier l8 do you ?

 

How do you tel if you identify an early L8 or a later L8.

 

The L8 had a red label YBJ (No cat) and green label for YBG (Cat)

I don't see why you wan't to change unless you want outputs such as the said ALS, LC or the likes of water injection which you stated you don't.

Theres nothing I know of that will make the car any better at 400HP with an L8 opposed to L6.

Red label still needs a knock sensor.
There's no difference in hardware between a red label and a green label.
You can run closed loop with an Oxygen sensor in a red label L8, just by setting the right variables in the software.
If the mapping is correct you can get the same amount of bhp from an L1, L6, L8 and P8.

 

If the mappings correct there iwll be ZERO advantage with closed loop, indeed it may even use more fuel on closed loop.
Best thing I ever did was junk my L6, and went K3 Emerald, correctly mapped, pisses the mot emissions at 0.97% CO, 137PPM, with nearly 190,000 miles on it, and 40+ mpg on a run not trying esp hard for it, smoothness and driveability are in a different league compared with the previous mapped L6.

I believe ive heard the l8 has twice as many "mapping points" so it will make a smoother ride, but it might just ave been badly mapped then. Also heard the l6 doesnt cope very well with big injectors?

Aiming for 450, turbo is good for 500 but the rest might not be lol so happy with 400 if thats were ill end up Which injectors would you suggest?

Tell me more about T2, what is it, price, where do i get it and why.

 

L1, L6 and L8 all have a Fuel table of 13x16 and an Ignition table of 8x16.
No difference in mapping points there.
T2 is an after-market ecu from Pectel, expensive but very good.
See: https://passionford.com/forum/ford-r...anagement.html

 

The mapping points are the same, but it is twice faster than l6
Here is one 3door cossie mapped on l6, just some days ago, here in Norway.
This must be a very drivable car

3100rpm - 413 nm
3600rpm - 502 nm
4500rpm - 603 nm

4000rpm - 311 hk

mak hk 450/max nm 614

 

Ahh i see, must have mixed it up

Well, twice as fast sounds good but what benefits does that really give IRL so to say?

Impressive figures that, what are the engine specs?

 

L8 uses the same microprocessor and crystal as the L6. So, it it just as fast.

It's the P8 that is faster, because it has a better microprocessor. The theory is that a faster microprocessor would be more accurate. But I've found that the mapping is far more important.

 

Here it is:
ported head"500 hk"(EBB)
CW2 cams
adjust campulleys
custom inlet
rs 500 cooler
pukkelrygg chip
GT3071R, ext 50mm wastegate(turbokongen) custom ex manifold
909 pistons and conrods
oe crank
200 block std bor
19 rad mocal oilcooler
tilton 2-plated clutch

 

Cams are adjust to get low down power
Here is dynapack reading:

o/min Nm hk bar
3100 413 186 1.44
3600 502 258 1.58
4000 547 311 1.65
4500 603 386 1.87
4700 614 411 1.86 -> Maks nm.
5200 587 434 1.84
6000 527 450 1.82 -> Maks hk.
6500 477 441 1.80
7000 425 423 1.76

 

Wonder where i´ll end up in power, std cams and pulleys, 7.2comp cp pistons and h-section rods ,all balanced, head ported on inletside and matched inlet, MSD 6al amplifier, big turbo, 70mm rs500 ic. Rest is pretty much stock.

Think ill stick with the L6 though.

 

The guy ho map the car i told about, have done some great mapping of Swedish cars to, one of them was smashed just two weeks after mapping.
What kind of turbo do you have??

cheers Geir Rune

 

Its standard at the moment, just rebuilt it, have not driven it yet, it does not have an ECU in it at the moment but i want closed loop, anti lag and launch control, Just not at the moment, just want to get it on the road and use it for a while. I also want to replace the loom so want everything in place so i know what i need to order when i get the new loom.

 

What he said although L8 does has double the memory of L6!, if you do want CL, ALS etc then go L8.

Martin

 

Its a hpx500 from turboservice.se/no good for about 500hp i think. Does ha map on a rolling road or on the street? What does he charge?

 

Oki, i have a gt3076 whit 63 exhaust for my new engine.
He mostly map on dynapack, it`s a lot easyer then on the Norwegian roads. It`s not his dynapack, so you have to pay rent for this also, but he is cheap on mapping and chips, he have made some chips for me, for some testing, they are free. I think you will come long whit 550-600£ total for dynapack and mapping. It depends on how ready everything is on your car, often it`s come up problems because of things aren`t right on the car, then it`s take much longer time. He lives a bit north from Oslo, not long from Sweden
