Which MAP sensor you use is extremely important as it definitely affects the boost comp setup and more. Especially the boost comp. Just selecting the MAP sensor in the wizard does NOT reset all the parameters affected by its range, so you have to be careful.

The GM MAP sensor is reputed to be a bit inaccurate, but I used one for about a year with no issues.

I pretty much now use the 5Bar AEM sensor exclusively for everything with boost. Its a medical grade sensor and despite the "concerns" over resolution I havent had an issue yet. Basically I just change the load points in the setup to what I want per application.

obivously you have to cut and paste the specific load sites you had and change your maps for the sensor but if your just starting it makes absolutly no difference and thats what he was asking

ok so this is going to sound a little weird, i lost my HD a while ago and now i need logs of my car back when it was on 13gs and running amazing on the AEM and im wondering if any else has some of my logs, i know over the last 2 years i have sent people tons of shit including logs and now i really need a copy of any logs of my car lol

[FastOldGuy]

You sent me one for my car with 13G's 2-3 months ago do you think that might be what you need?

[pengulns2001]

im looking for logs not cals but thanks.... if by chance i sent you a log then yes i definatly need it

Anyone else using the GM boost solenoid too? Here's what I've done so far.
My solenoid is connected so that it interrupts the airflow between the turbocharger's output and the wastegate (just like we typically do with other electronic boost controllers).

If you look at my Boost WG Base Duty map, you'll see that I have 84.4% duty cycle for zero psi and under. Frankly, it doesn't matter what you put here, as the wastegate won't move at vacuum pressure. 84.4% keeps the GM solenoid quiet, and is what GM/AEM recommends as maximum duty cycle. However, one of the AEM engineers uses his at 100% with no ill effects. Therefore, I keep my solenoid 100% closed for 0-10.1psi for maximum spoolup. All pressure between 12-18psi uses a roughly dialed in duty cycle; this area needs a little more work. And for safety, 20+ psi has minimum duty cycle in case my fuel cut load @ 18.5 psi doesn't work.

Why not keep the solenoid turned off when below say 3 psi of boost? You are just wearing out your solenoid for no reason.

ok so im doing free dyno tuning in the detroit area, i need some before and after pulls to get a job so anyone around detroit within 1.5 hours if you need your car tuned on the dyno i will do it for free

[BAdAzZV8]

Dang man, come to FL, haha

[Mark Hindelang]

id love to take you up ont he dyno for free, infact if your offer is still up in another month and few days, ill be calling you
