B6 question

[Ruben MX-3]

hey ppl, anyone know of any different ecu's that would fit our cars stock B6 wiring harness for more power?

[Joe Carlson]

I'm not sure, but i think you can use the bp ecu and get quite a bit more power. you can use alot of peices off of the bp to get more power, but you know i'm not totally sure.

Thanks-Joe

if you have the 92-93 sohc then you can swap between the BP. if you have the 94-95, your pretty much screwed. the 94-95 is only swapable to itself. other than a few misc parts like the distributor, injectors and such. but no ECU swap.

[Ruben MX-3]

SIGH!!!! THANKS ANYWAYS GUYS!
ciao

[m92_MX3]

so i can take any ECU out of a BP and put it in my 92 SOHC and get more power ?

[Marlon]

NO!!!!!!!!!
don't do it

[manowar821]

LOL, YES OR NO!
Because I hate my sohc 92 ECU.

Thankyou ^_^

[m92_MX3]

why ? what happends if i do it ? whats bad ?

[OsoSlo z28]

it's a difference of 200cc. you have a completely different engine that has different needs than a bp motor. the bp has a different pulse width along with a different size injector and is not a good thing on a stock b6 motor. (intake/exhaust is still stock)

the only time you see a benefit from using the bp ecu is when you have internal engine work done or a bp/b6t motor swap. this helps with a better fuel curve to work with.

[m92_MX3]

so i would mess my motor up what if i have bigger injectors ?

[OsoSlo z28]

if you don't have a substantial increase of air coming into the motor, it would run like crap.

[m92_MX3]

so something more then cold air intake, like a turbo or some other type of forced induction ?

[projectmx]

what about swaping the dohc ecu out for the miata ecu?

[Ruben MX-3]

tru... wud the miata ecu work?

[torpedan]

For the majority of intents and purposes you can not just swap the ECU. VArious sensors and at times full wiring harnesses must be adapted as well.

A miata uses DIS, you would have to swap that over as well to use a Miata ECU. This very likly modifying the wiring harness as of the engine in the mx3 sits transverse.
