does anyone know if you can use the cosmo ecu or do i have to use my tll ecu and do i need to use my tll wiring harness or can i use the cosmo harness please let me know thank you

 

lol. I wouldn't be using either (and I didnt).

But if you had t try and use a stock one stick with the cosmo one (especially if trying to keep the twins). Will be different wiring to your stock harness as well. So is almost a start again job regardless.

 

Stock ecu is a wreck to install. You can use a s5 TII harness and ecu with the FC turbo.

 

hmmm id very much doubt that.
The emissions are different and work on the twin's sequential system.
The porting is massively different between the 2 blocks, therefore fuel maps will be out.
Cosmo ECU has knock sensor inputs as well.
TPS is full range, should be ok with S5 ecu.
EOMP wiring should work on both. But S5 is 4omp injectors , cosmo block is 2 but shouldn't matter.
Sensors dont know about... I got rid of the cosmo ones and use the haltech ones.

Meh why bother, get a haltech/ microtech for $300 and dont have the head f$ck.

 

where can i get a microtech for 300 that was the origanal plain but ran out of money but if you can find me the microtech for 300 i'm in there lol and thanks for the replies guy

 

oh yea i heard about megasquirt has any of you guys heard of using it
