i got a 92 vx and for some odd reason they put in a p28. lmao. theres some kinda vtec but its pretty funny. the rpm climb super slow even in 1st and when i hit like 5500 or somthign a instant burst of... i wouldnt say speed but the rpm jumps. but for sure its not running right. is this just the ecu? has anyone else tried a p28 on a vx motor? what ecu goes with the vx?

btw i bought this for $850 from some mexicans. haha

 

you need the p07 ecu witch i have,pm if you want it

 

whats making the p28 not work with the vx motor?

 

Its just plain not the right ECU, fuel and timing maps are different, the D15Z1 in the VX is a Vtec-e engine, its not normal vtec and its designed for fuel economy. The P07 is also setup to use a 5 wire wideband O2 sensor and an EGR valve.

 

does the engine clock say d15z1? if it does and the head is a z1 head, then yes you need to change the ecu. and ont get on it or rev it out until you. it will break your motor!
