Hondata

Hi guys,

My friend has had some issues with fueling for his car, i dont think its to do with the s300 though.

Everything has been put back to stock apart from it has a turbo kit and s300 running stock B16 map.

The problem is it just runs rich all the time, at idle it runs 10.1 AFR's.

Any suggestions?

Thanks
Yasir

Are the injectors the same size as listed in fuel trim? Also, check the ECT Compensation.

Yep 240/240 in fuel trim and ECT compensation is in the middle

I'm not sure i understand your first post. The car is currently a stock B16 engine with turbo kit?

Yep,

stock b16 with turbo kit and hondata s300.

You need to get it tuned. Start taking fuel out and it should lean out.

Yep, ive been trying to lean the maps out but it dont seem to be doing anything. However just today i connected up a po8 i had lying around and it was idling nicely at 14.5-14.8. Also ive blown the ecu fuse 2 times. So could this be something blown in the ecu or faulty s300?

Blown fuses indicate faulty wiring and you need to troublshoot that first.

Orite well my dad socketed the ecu, when we 1st started to crank the car abit of smoke came from near the ecu. but then after that ive driven the car a few times and tried to map it.

So ill have to get my dad to take the s300 stuff out and put it another ecu? will a po8 be fine?, i noticed somethings missing compared to the ecu im using now.

Get an adjustable fuel pressure guage and tune it to help reduce the amount of fuel pressure.

An s300 will not work in a JDM ECU. S300's only ork in US ecu's. For a JDM ECU you will need th s300j.
