i just got my b20/vtec swap in. it came with a chipped p28 and dont want to run and idle's really rough and wont rev without sputtering. i can plug my ecu that was running my d series and it idles up and down and can be driven but at low rpm's it cuts out. i pluged my friends 97 hx ecu in and it still idles up and down but runs alot better. any usefull help will be repped.

I would fix it.. ;) .. But it seems you may have plugs backwards, Its not uncommon for people to do.. I would check the Map and TPS since thats the one most people have backwards.. If your sure the are right then check all plug connections, vaccum lines, leaks, etc.. Get that bulb fixed also.. :cheers:

i checked the check engine light code and i counted 58 1 second flashes with about 5 or 6 seconds between flashes with the ecu that ran my d series. so with that many flashes that far apart. was it telling me it was a code 10? if so thats the IAT sensor. i will check it tomorrow with the p28.

if it doesnt come on when you first turn the key, it's broken.

seriously have check everything just a once over to be sure. mainly all the connectors that have the same plugs.

58 1 second flashes :thinking:


there is a delayed flash and a quick flash..

delayed flash = 10
quick flash = 1

If there is more than 1 code there will be an even bigger delay for the next code. You know your done when you get the same code twice...

The IAT and the IACV connectors look a lot alike on the harness (that 2 pin barrel connector)

Generally when they are switched, it will blow Q31 in the ECU, and then you will obtain a solid CEL, which means the ECU is bad as stated earlier-

Hopefully its just the chip that Xenocron made- Im still waiting to hear back from him-

how do i check the ecu? i used my friends ecu in mine and put it back in his and his still runs fine.

is it an obd 2 throttle body? if you are running an obd1 ecu youll need an obd 1 tps.we usually have to change to an obd1 to get it right if it is. something about the wires pinned different. also the iacv and intake air temp sensor and that little spool valve that has a plug and lets vacume to the purge canister. and the map and tps will interchange as well...

well i picked up a 97 b20 throttle body today and i am swaping everything like the map sensor and the tps sensor over to it tomorrow.
