Blitz controller manual/auto/gain

[Mario65]

Anyone using one and found a nice setting that is a safe gain and % on the wastegate?

Once you move from auto to manual it deals in percentages and not total boost. It also gives you gain control for spoolup.

I havent WOT it yet and found a high gain is great if your just gonna stay around 12 PSI. when I go higher I just want a little more info before I try it.

Im in the same boat with my Greddy unit. I have yet to seriously play with mine and still trying to figure things out and how to use this stupid thing correctly without blowing up my truck.

I keep gain around 10%. I reach full boost by the end of first gear (or very close) so I really don't have much need for it.

I've never been able to get mine to work properly in auto mode, I run in manual. To translate the % to boost in manual mode, I do the following. Start around 40mph in 3rd gear and slowly ease into the throttle eventually heading to WOT while watching the boost gauge very carefully for signs of overboosting. The Blitz will record the max. boost level. Easing into boost in 3rd while keeping an eye on your boost gauge should give you plenty of time to let out of the throttle if you see your boost gauge spike.

I start at 10%, then make another pass at 20%, 30%, and so on. The increase in boost every 10% is not linear on my truck, but close from 10%-60%. After that it gets less and less linear. This will give you a nice "cheat sheet" to use to dial in your boost. The Blitz keeps things pretty tight from that point forward unless you change something.

HTH.

I dont know what values I had on the top of my head, but what I did have, I saw 21.4psi from a 70mph roll-on the other night... yikes!

Ive reset my whole entire controller to 0 for any setting related to boost. I've also turned out my WG rod about 4 turns just for some security after seeing that 21psi hit. Truck isnt tuned to see any serious boost yet... thankfully, I was out of it quick, so the 21psi was just for a split second....but then with these trucks thats all it takes. Ran fine the rest of the night though... I just kept my foot outta it :tup:

Re: Blitz controller manual/auto/gain

I think I am going to wait until shindig before I run it manual. I think Ill just leave it on auto and set it at 13 until I can get a sharp tuner watching it.
