yes, 14.7 was before they got on the throttle. Do you know what should be the voltage? or do you know where I can get instruction on adjusting the ESM? thanks

I have mine set at 2.8VDC. Also, be sure to have the power leads connected as the instructions dictate.

 

 

I see that you have lower your voltage setting, did you set it low after the installation of your high boost pulley, or did it run better with it set at 2.8 Volts and not 2.93 Volts? Oh, ogolden1 where did you dyno your car? XSengineering?

 

I did it because of an occurrence. The car does pull timing when the ECU senses a MAP signal which is close to or above the barometric pressure. The ECU has a barometric pressure sensor in it to monitor ambient pressure and I think the ECU compares the two values (Baro and MAP) when it tries to determine if there is too much manifold pressure and pulls timing.

The car had been fine but one day I was driving into the office and it was nasty out. A storm had just moved in and the Baro had dropped out significantly; I believe it was down around 29.4 inHg. Every time I got into boost the car would bog just like it would when I turned up the ESM setting. When I got to the office I turned the ESM done, went for a drive and everything was normal again.

I left it down around 29.0 inHg just to be safe. It would take some noticeable altitude changes or a hurricane coming through to drop the Baro down enough to affect it again.

As for fueling, with the IMRC disconnected no knock was present and the fuel pressure is high enough to support the fueling needs to where that slightly lower pulse width won't be an issue.

 

Comptech referred me to Autowave Inc. in Huntington Beach (as I'm in Orange County.) They are an authorized Comptech installation Dealer. They had 3 NXS's there. They use a Dyno Dynamics Dyno, which is more accurate than the Dynojet Dyno.
