ok im puttin a pr3 vtec head on my obdo b18b1 havent started yet have stock ls head on the car but i sold my pr4 ecu and put a pm6 chipped to pr3 with one wire zdyne will this run my car for now now heres the problem from idle to 2,000 is fine but from 2,000 to 5,000 is a dead spot boggs down and 5,000 to 7,000 runs great is it because i need to put the pr3 head on or do you think there is something wrong with this ecu

 

Its because you have a non vtec car and your trying to run a vtec ecu.....

 

LOL

such a simple but true answer

it never surprises me at some of the questions we receive on here

 

Should've had a v8.
Once you put a non-vtec ecu back in, you should have no problems.

 

Let me tell ya... you're going to be disappointed with the results... Here's why.

Stock head on stock block.
OBD0
Stock head on stock block.

Atleast rebuild, bump compression up a little, and convert to OBD1

Get a OBD0 PR4 for now however.

 

im not retarded i have everything to do conversion i just wanted to make sure my ecu was good. i didnt need any smart *** comments

 

Smartass or truth take it as you will... just stating a fact a stock block LSvtec is a waste of time and money.

Been there, done that.

 

we could explain why stock ls or b20 block vtec builds are nick named "time bombs" if you would like
