Andrew, just out of interest, do you use the 30Hz or 31Hz for the boost wg frequency? I could not find any 30Hz option in the ems.

I will be using the GM solenoid. It should be similar to the apexi just cheaper Andrew, how difficult was it to setup? Any tips?

 

I'm using the GM boost control solenoid. VERY easy to setup and use, but I'm not playing with the feedback circuit YET. If you want to check out my map, send me your e-mail via PM and I'll get it to you. Only issue so far was that I had to specify a TPS level at which the PWM outputs switche from IAC to boost. I messed this up one time and it drove me crazy trying to track down the problem.

I'm planning on playing with the injector timing VERY soon. . . . and boost comp, and boost feedback and...

timq and andy, do you have any tips on tuning the "Base waste gate duty map" ?

 

I'll send out the maps tomorrow when I get back to work (I'm using my work laptop to tune- my personal doesn't have a serial port!)

There is some very good AEM documentation on tuning the base wg duty cycle map. I based my map on the AEM instructions with some minor tuning afterwards to get my boost levels correct. In a sense, I am using boost feedback because by 9 psi my WG duty cycle drops back to the min, but around 7 psi it's 60%. I've designed it so that if it comes above the desired boost it automatically comes back without using the boost feedback controls.

Sorry mate, I didn't do my own MAPing I had a go but I dont have enough patience when using anything electrical & I probably would have ended up smashing the laptop to pieces so I thought it would be cheaper in the long run for a pro to do it
