Max MAF signal with alcohol?
I am trying to ballpark what my highest MAF reading will be when running alky.
Current setup:
Stock Turbo, stock inlet pipe, MAF ~ 1820 @ 7200 rpms and 21 psi.
Future setup:
HFS-5 alchy kit planning to run ~ 26 psi dropping to ?(I don't know how much I will be able to hold)
I would like to get a ball park idea of how much higher the MAF reading is going to be so that I can rescale my tuning tables now rather than keep rescaling as I slowly up the boost. Anyone have an idea or better yet comparable data?
Another question: Is there a way to control a +12 output like the auxilary solenoid but individually with each map rather than globally? I would like to turn on and off the alky kit by selecting a map on the UTEC.
Thanks

Sorry - there isn't much reason to look here anymore...
Using the UTEC logging, I have seen over 2100 on the MAF at 24+psi.
Here is a log of a 1-2-3 gear pull, uphill to force increased loading (I was checking knock).

Hehe - and it will probably take a week for you to discover somebody answered...

Thanks man, but what turbo are you running? It looks like it spools way to slow to be a stocker.

You'd think it was bigger, but it's an Evogreen.
I was clinbing a fairly steep hill to place a great deal of "load" on the car for the logging.

I agree that full boost is much much too late, even for an EvoGreen. The fact that you were going uphill is even worse -- that should make it spool faster relative to RPM (like being in a higher gear).

Yeah, I'm still fighting with minor boost leaks.
I'm getting ready to order replacement seals for my TB shaft. Thing hisses like a pissed snake at 6psi.
