Fuel cut sucks.

**Intropy** · 03-21-2012, 02:16 AM

I just ate the steering wheel. I had fuel cut set for 21psi and made that by 4500rpms. Was not expecting that.

I'm making some really good power with a great powerband but she is getting a bit noisy.

Making 15psi @3500rpms and over 20psi @4500RPMs.
AFRs pegged at 12.0, timing around 16 degrees on E85.

Raw knock of ~3v. I'm getting nervous about that, but I do have a built engine and solid mounts. Any AEM guys have comparable numbers?

It feels like someone hitting the car with a sledge hammer.

I just had a thought. It'd be very easy to rescale fuel cut in the stock ecu to be PSI based instead of Load based.

I was so pissed the first time...pulling out in traffic.

These engines are a bit noisy to begin with, but 3.0v is definitely at the point of concern. How much timing at peak tq and redline?

you have enough pump for e85? i could have sworn i seen your car in the jackhammer dual pump hanger video i have lol. i want run e85 as well but u cant really read knock which scares me even with a built motor. and i already have the injectors for my setup which kind of sucks cause im only gonna b on the arc2. so your out of fuel?
