Decided to get my hondata tuned earlier and after just reading the current chip for data, my ecu started to do somewhat of a count down upon start up. Throwing codes like 1, 2, 3 and so on. We reset the ecu, still the same problem. Finally, we installed a stock PR3 chip and code went away but obviously, with the mods I have this will not work...We then burned another chip with the same maps but at open loop...it kinda worked but for some reason I'm getting a code for knock sensor and car bogs between 5000-5500 rpm and runs lean at high rpm (above 8500). I wonder if this is just a wiring issue (current wire harness from hasport is a piece of crap and cracks in all places) or nonobd pr3 and hondata is a bad combo to begin with...btw, my car was running fine with no codes whatsoever before getting it retuned. I should have just left it alone I gained 2 whp though, hehe...from 196.0 to 198.2 whp and 132 torque.

 

no Hondata gurus around here?

 

convert to 92-95 spec.
get a p28 ecu

 

I'm going to replace my current wire harness in the meantime and see how it goes...I figure if I convert to obd1 now and there are wiring issues, it will probably ground itself out too. But I will definitely ditch the pr3 in the future. thanks

 

what kind of times have u ran?

 

not into drag racing...but I plan on taking my car to the track soon, just to find out. I expect mid to low 12's with a good pair of slicks and of course good driving.

 

Only one problem came up with my own stage 2 PR3 Hondata. CYP sensor CEL. Turned out to be a basd wiring.. Solved the problem when we replaced the engine with B20VTEC from a B16. Bad connection from the connectors it seemed.

 

ic...hopefully, the new harness that I ordered arrive soon so I can replace this piece of crap and finally get on with tuning. If I can only make it to 200 whp then I can stop for awhile NOT! I'm almost there though, then what's next, hehe...

 

Kotsemoto,

I was wondering if you have had any idle/warm start-up problems with your PR3/Stage 2B set-up.

I am using a PR3/Stage 2B in my b18c1 turbo '89 CRX.

If you have had any problems, please let me know how you fixed it.

Thanks.

 

Build your own harness. It takes time but it is cheaper and kinda fun.
