I would never run anything under 93 unless you live very high above sea level.


Thanks again

ok, so how about california where 93 is non existant? period?

I would think it will depend on where you drive. Are you at sea level or up in the hills? Less octane means less timing and maybe less boost. It is all in the tune.

The good thing is the MAF will help with air pressure changes. The great thing is the MPI Tuner will help you fine tune for anything the MAF does not.


Thanks again

chaz--I see you are retarding 9 degrees up top in the WOT column, seems a bit much! If you take the -5 in the WOT column and add the -4 in the IGN AMP column you are taking out 9 degrees. I had this on mine and when I got rid of the IGN AMP value I think I noticed a difference, but can't be positive. If you look at Beavis' ignition map he only has -3 at the top with nothing in the IGN AMP column and that's with an MP3 ECU and the J&S telling him where nock is.

Everything else looks good though. I see you also made your analog values in the WOT column to an 8 from a 7. I think I can actually go with a 9 up there since I am only about 4.7 volts or so. That will give you some more fuel, but don't know if it's needed or not. I think the 9 will be right at the 4.8 to 4.9 volts mark. Is this with your fuel cal at 7? How does she idle, good?

Well..Today i was at Modern Performance. Got to install my inline fuel pump. It's an MSD INline Fuel Pump. Had some problems installin but i followed Flyin Protege manual..And got it installed.

When we finished it was already 8pm. So we didn't have time for the EBC. Hopefully Before Dyno Day.

Well when i was driving home..the car was buckin..and just driving like total donkey s***. As soon as i hit boost the car would buck violently...Well..i pulled over..and loaded an old map. And did a little tuning.

Car began driving well..But way to rich..I was runnin 11.6 a/f in all gears.
I am going over a datalog i did right now.

Please take a look at my new maps..If you could..please take a second to email me..and i will send you a datalog.

Try taking out the ACT from the intake tube. See if that makes a change.


Thanks again

Act? Don't they make clutches..LOL.

Are you talking about the Intake Air Temp Sensor that we put after the MaF?

I am gonna email you my datalog..

But if i take that out. It will cause a vaccum leak?
Since it's after the maf.

I am plannin to tune more tomm. Hopefully i will have better numbers.
I am going with some lower numbers..and will post the new maps in a couple of min.
