i have a crx with a mini me swap and bumped up c/r. it runs way to lean, and i have a set of 450cc injectors(dsm blue tops), but i'm not sure if i can use them with a stock honda pm7 ecu. i have stock injectors now, and they need to go soon! any ideas? i also have a fuel pressure regulator that has been cranked all the way up, and it's still too lean. any ideas would be greatly appreciated before my new motor goes nuclear.

 

You are correct, you stock ECU will not know what to do with the 450cc injectors wihtout some aid.

There is no way in hell you're running lean with the fuel pressure cranked all the way up. This is N/A right? You're not trying to boost with no fuel management are you?

It is n/a, but it's got around 11.5:1 c/r. I retarded my cam timing about 2 degrees, just to see what would happen, but as far as fuel goes, my plugs are turning white. Now it was a dx, so i don't know if the fuel pump can't handle it or not(never got enough money to upgrade it yet, even though my autometer a/f guage says i run rich at wot(overpriced light show if u ask me). What could i do to use the dsm's? The cheaper the better right now, since i'm on a verrrryyy tight budget. lol
