I have a bluebird motor to swap in my 91 senta. I put on the usdm TPS but the ecu is an auto ecu (I think? The letters on it are BJ)Can i still run this without any problems?:help

no it will not you unless you get afc and lean it all the way out or you could get a jwt reprogrammed ecu made for your setup

Is it a JDM ECU or USDM ECU?

Also please don't double post. This is a technical question and its being moved to the technical section and your other post has been deleted. Thank you!

it is a jdm u13 ecu

Does anyone know if it I can run a U13 AUTO ECU on a U13 engine going in a 91 Sentra SE-R that is a 5 SPEED? Any help is appreciated. Thanks to the guys above for replying and I double posted to find an answer sooner. Sorry.

The U13 ECU must be used with the U13 maf or a GTi-R maf but can use the USDM O2 sensor. All JDM ECUs want to use the JDM coolant temp sensors. Yes you can use it on your 5speed, as long as you stick with the parts listed as well. Make sure you change over to the USDM TPS.

Cool thanks a million RED_DET! Thats what i needed to know should have be driving her tommorow!:pface

I have tried to tune it down using an afc but i have to really, really take it down to get it to halfway idle right but it still is fluctuating at idle between 750 and 1000 rpm. It is still very rich. It has lumpy idle and billows black smoke from unburnt gas when you give it any gas. This is only at idle on top its fine. Im still running the auto ecu, usdm tps, and jdm water temp sender. the maf is supposed to be from a bluebird. Any suggestions on how to better tune this, I just cant see how it is this rich on the bottom. Also this is with a stock se-r pump (cant go over 5lbs) my exhaust is ran out the side by the front tire i know this is probally effecting the performance as well being there is no backpressure for the o2 sensor to get to a good reading probally as well. Im stumped guys please help!
