Hi all, i am having a problem with my engine and have no idea what it could be and am after some advice. I have an A15 which is fuel injected and running a T28 turbo. It has an ems computer and electronic ignition running a single coil. The previous issue was when i would run more than 6psi the car would cut out under load. EMS said that i needed a CDI unit as the spark wasnt strong enough and i installed a CDI. Now it is ok up to 16psi but is still doing the same thing when running more than that. Has anyone got any ideas or has anyone experienced this problem before? Any feedback will be much appreciated. Cheers

have you had it dyno tuned if not i would highly sugest it

yeah its been on the dyno 4 times, its getting plenty of fuel and the computer is getting constant power

What plug gap r u running? Might need to close it up a touch. Mind you 16 psi is nice!!

already tried playing with plugs, didnt help at all. i was thinking maybe its the coil or dizzy.

I would be checking the dizzy or coil. Running higher boost you need to run a closer plug gap and stronger spark other wise the pressure can "blow the spark out"! You may need a stonger coil ect.

yeah im only running a single bosch coil at the moment. i was thinking of getting a procomp coil from ebay, has anyone got one and are they any good?

My advice would be to stay clear of Pro Comp, I have had a few problems with their dizzys and a freind of mine had drams with his whole Pro Comp set up. Crane Fireball, MSD or even ACCEL (the big yellow sucker) would be better even though they are a few more bucks.

Thats just my 2 cents

I have a Crane Fireball on my Ski boat, good unit! MSD would also be a good choice.

thanks for that ill try them out then
