Unreliable power on Diablo

[vld]

Had Diablo for about 5 months now and the power has always been spotty. Great when the motor is cool, purely lethargic when the motor is hot. I am running max timing and wot fuel trim. Any ideas what may be causeing this?

^^ Your maxed out values is likely the cause. Too hot, too much timing, and too little fuel.

Definately do not max the fuel to the lean side...that is crazy not knowing where you are at. If you leave the fuel as-is and max the timing you will be fine.

you want to reduce your timing from maxed out in the heat. Beacuase if you have it too advanced, the computer is having to pull timing the whole time.

You may also want to run a cooler thermostat (160* - 180*??). DON'T max your values unless you are dyno'd.

also make sure your software version is the latest from diablos website. I updated mine and it fixed the problem you described.

Timing will be all over the place regardless. Setting timing isn't as straight forward as just picking a number. The EEC is constantly changing timing based on ECT, ACT, load, and several other things.

I just didn't want you to be confused when you back it off and it is still al over the place.

did you check to make sure your software version was updated?

 

[vld]
