My haltech E6X cuts out HIGH 3rd, 4th, BIG BACK FIRE. I dyno'd and got a decent run with a small cut out (450hp), but I have to fix the cut out.

I believe the ignition shuts off for a split second(about 7-9rpm) and returns with big back fire, loose all power when it does.

I went through the software and made sure all my inputs were right, timings right...

Is it a bad coil, igniter, not enough juice?

If anyone has a good idea please respond.

Thanks,

the rpm's aren't spiking to 16k when you datalog it are they?

 

you aren't running very rich are you? When I had my maps really rich at 10 psi in 4th it would just drop all power and then back fire... sounds pretty similar with what you are experiencing. What are your afr's and egt's when this cutout occurs?

 

NGK PLUGS, about 11.8 afr, i will check for spiking in my dataloging.

I just broke the front iron housing, upper dowel pin cracked housing, right were the oil feed is and shot oil all over my engine, I was like wow thats not good.

I will be installing a serious dowel pin mod for my next engine.

 

too lean with too much timing.
