hey wats up yall i bought this ecu that soposedly was chipped and i was driving it but it will not go past 6k the ecu is a p72 obd2a and for now im runnning an ls motor is the ecu bad or is it a safety mechanism that i am sopose to use in a v tech motor thanks in advance

 

why are you using a vtec ecu on a non-vtec motor? what kind of chip does it have? is it one of those ebay chips, or socket/chip type of setup that's been tuned? your cel should be on, and it might be putting the ecu in limp mode, which would give you a lower redline.

 

I think it because you dont have a vtec motor, but could also be ignition coil also.

 

i am using this ecu because i want to go ls v , the chip is soposedly a skunk 2 , the tune soposedly an all motor stage 3 and if its in limp mode how do i fix it

 

id recomend using a stock ecu or a non vtec ecu untill you have a motor that demands such mods. sorry just my 0.02

 

i'd definitely switch back to a stock ecu. obd2 ecus can't be chipped, so either the ecu you're using isn't obd2 or it's not chipped. once you're ready to tune your motor get a obd1 ecu and socket/chip it.
