I have a 90 crx with a b16a swap. Bought the car with the swap allready done but noticed that the car was allways running fat (rich). Found out to be the ecu was the wrong type for my b16a v-tech it was for a 89 ls integra. So got a hold of a pr3 I was told this would fix my problem and run my v-tech correctly. Well i put the ecu in and it doesnt run rich but has very little throttle responce. what could be the problem?

 

uh oh... another v-tech... hello? welcome to HT, mang...

no codes?

have not checked for codes yet just got the ecu saterday.

 

try checking the wiring on the TPS sensor. if you didnt switch the wires around then they could be backwarks still. i ran into the same problem. also try checking hte O2 sensors the top one should be the primary which i think is the white one. if the O2 sensors are switched then you will notice a slight drop in throttle response but most likely its going to be the tps sensor.

 

Thank I will try that and see what happens.

 

how about your map sensor? do you have a vaccum line running from the map sensor to the top of the throttle body? i had the same problem but i was throwin code #5 and i did this to remedy it.

 

well i think I found the problem my timming belt jumped a tooth.so i have to replace that and throttle position is wrong. Will see if that is what it is.
