I put an Eaton 62 supercharger on a 1995 Accord F22 B2 engine. It ran with the stock injectors and ECU but seemed starved for fuel. I added DSM Blue top injectors which I think are 450 cc. I also put in a chipped ECU. It now starts, runs about 2 minutes until it is just starting to warm up. It revs and idles very well until that moment when it runs roughly and dies. It will fire when cranked but will not start, it seems like it almost will start but just can't quite get going. I put the old ECU back in which didnt' help. I put the old injectors in and it starts. I put the chipped ECU in with the standard injectors and it works. I put the big injectors back in, intalled a high pressure, high volume fuel pump in the main gas line just outside the tank but again, no help.

What is going on? It seems to be something with the injectors? I am using the Honda injector resistor box. It seems like a sensor does something at 2 minutes when it warms up and changes the engine timing. could it be flooding from the big injectors? I have to let it sit until the engine is stone cold to get it to restart but again, it runs only 2 minutes.

What map is on the ecu? Sounds like it is flooding itself out to me.

 

That's what I was thinking. When the engine is cold, it HAS to run rich to stay started, and it needs a lot of extra fuel. But when it warms up, it is still too rich, and bogs itself out. I'd say you need a good dyno tune, and it should be fine.

 

Thanks, I will give it a try.
