Rb20Det Ecu Abilities

[poeticjustice88]

Hey all,

I have read on a couple of different forums that the standard rb20det ECU has some tuning capabilities. None of them went into detail to say what type of capabilities though.

I was wondering if it is worth getting a dyno tune on a standard rb20det ECU and what type of things can be changed. Like, does it have the ability to run bigger injectors, different timing, higher boost applications, these kind of things.

I ask because my car is not running right, but it is not throwing any codes with the led on ecu. i believe it is an over or under fueling issue, but i do not want to put it on a dyno if the ecu cant be retuned

Kind Regards,

Michael

you cant "dyno tune "a standard rb20det ecu

but you can get the ecu NIStuned which will enable you change fuel/ignition maps etc

Thanks for the reply

Another question, is it worth a dyno run for fault finding with the standard ecu?

The prob I am having is when I hit boost at WOT, I see about 5 pounds until the engine just bogs down and doesnt use the boost. If I accel at say half throttle I can get it all the way but at WOT it just doesnt use the boost.

I am curious as to whether I should stick it on a dyno to find the problem, or if I should fault find the hard way

Kind Regards,

Michael

chuck it on a dyno

that way you can check other things like the AFRs while its there

Sorry to hijack thread.. But I got my r32 (rb20det) tuned with a 'chiptorque' branded chip which was the tuner's shop name that dealt with my car.

My question is would it just be a nistune with a chiptorque sticker..? If that makes any sense

I have been told after this was done that they are not the right tuners for imports etc.

The guy that tuned my car said it's NOT a nistune.

open up the ECU and have a look if you can see a brand anywhere
