Ok guys im a complete ECU noob... My friend has a OBD2B to OBD1 conversion harness and ECU he would like to sell. It is tuned and currently running a base map type R program... I'm quite sure my car's stock ECU is OBD2B (correct me if im wrong), so will it work??? Also, what will the effect be on my engine (increase horsepower? higher revving?.... etc.)??????

 

You would need to tune it for your engine. You talking type r teg b18c motor. It will not run your f rite. It may work or you will have to swap back to a obd1 distributor with the 3 rotating sensors in it. Your motor has one rotating sensor in the distributor and 2 on the crank. I have run a h22 swapped in a civic with a chipped p28 before we did use the 2 on the crank and the one in the distributor but we could not set base timing the obd1 ecu is looking for all 3 sensor to rotate together when setting timing. Test it and see if it will even run. I would not drive it it is running fuel for a 1.8 liter your are running 2.3 = lean that is a bad effect.

Is is crome, hondata, ectune, neptune, uberdata................? If you are in the co. area I will tune it for you. All and all going obd1 is a good idea tuning is a good idea your ecu now is probably not optimizing that cai and the try y header you have.

 

Ok ok i know what your saying... So if i bought it, i would need it retuned basically correct?? He wants $200 CAD for the ECU and Adaptor harness, is that worth it even if i need to retune it? What are the good effects/ gains that doing this will get me? Thanks!

 

200 is a good deal for a chipped ecu and a harness. You better find some one that has done it I do not know it the accord engine harness is different then the rest as far as pin location. What ecu is it? I would test it in car first.

With a re tune (yes you need a re tune)
More hp
More tork
Better fuel economy if tuned rite
2 step aka launch control
3 step aka no lift shift
cel shift light
opens doors to a turbo, nitrous, super changers, itbs, bigger map sensors, bigger injectors, any tps (you can use a ford 5.0 tb) e85, dataloging, with a 2 timer and crome you can run e85 or 91, smother or hard vtec engagement, turning off some codes, rtp, If it a p72 it will have an extra out put that can be set a any rpm (lots options to use that).........................So much.
Look into
pgm-fi forums to get crome it is free to down load.

If you just get a chip burner you can re burn a base map.

Thy have some f base bins

I will be pissed if you dont come back and read all this it took a long time to tipe all this lol.
