no didn't change much on it at all, in tunerstudio under tool, then under trigger wizard, i had it set to 25 so i change the ignition offset angle(deg) back to 10.. this time it was getting both wheels not one like last time and rotted the intake.. my air temp was still 160 deg

Why was your offset at 25 and what made you change it to 10? So you pulled 15 degrees of timing out of it and picked up 4-5mph? Why do you always delete your pictures from photobucket after you post them here?
lol sorry about the delete of the pic's i didnt know thats deleting them would removed them from the sit i thought you were doing it cause they were to big or something.. i want do it any more now that i know im a dumb ass...
i set it to 25 i read it wrong, were it saids to mach the above with the timing light so i change it to 25, scoot said set it back to 10 so i did, the car runs alot better but its getting vary bad gas mileage. changing that had nothing to do with it, it was getting bad gas mileage before...
Im going to say no thats not what help the car out i ran it 22 times and was getting 9.3 at 78mph. with 2.5 60ft so i would say that the 2.2 60ft help me out alot and i started 2steping it at 1800rmp and it was getting posi this time.. last time i ran it my best 60ft was 2.5 and one wheel and i shut the car off and let it cool off it was running 230 deg. and it was later on in the night when i ran them 8.9,s at 81,82mph
The only "right" way to check it (since when using the timing map the commanded timing will probably jump around some), is to go into basic setup > more ignition options > then the top box you can select "use table" or "fixed timing". Choose fixed and it will stay at whatever "timing for fixed advance" box is set to. I like to set it to 20 since you have a big timing mark at 20 you can verify with the timing light. If the numbers don't match, turn the distributor until it does match.
that was how he had me set the timing on it and come to find out i had it off 4degs ms was reading 35 and i had the timing light on 39 so i bumped up the distributor to 35 on the timing light and did the fix timing table to 20 and it work out right so thank you having me check it again...
now i just need to fixed the vary rich problem.. the car is running 11.5 to 10 on the wideband just easing into the gas
Word on the street is that Scott also told you that his timing table you are running is too aggressive and you need to change it. Why are you so reluctant to lower the timing? I also heard you are wanting to spray it...spray with timing too high for just boost = double fail.
Scott told me just to pull 2 deg out of the hole timing chart.. he didnt say nothing about lowing it any more.. all im doing is sending my msq and datalog to him and doing whatever he saids to do to it,, is what im doing.. i dont know anything about tuning the thing..
but yes i was wanting to run spray on it but i was going to work on the timing 1st.. before the slicks part gets out with the 2.73 gear and my cheap clutch it will just rip it out thats why i want put slicks on it..
Im not running the timing talbe that i 1st show you iv made changes to it..

your taking that the wrong way, he goes over the msq and datalog and tells me what to change. your just wanting me to fix the timing.. iv not missed with the car senses the track.. im going to try to get it to the track tomorrow and i will change anything you like..
mine in 1st gear dont boost until 4k so if i pull the timing the car want pull its on ass 2nd gear is arond 3200,3500rpm, 4th gear at 2000rpms i get on it will will make 15psi at 3000rpm.. if this helps you rethink any on the timing table for my set up
so if anything haves to be change on it i cant do it i dont know what does what really and getting the ms2 ket was over my head
but scotts going over my hole tune that why iv been going with what he is saying.

Well, you need to either listen to him or I because our advise will be different. You've got to make choice of one or the other, not both.
I've compiled 6+ years of research to gather as much timing map as I can, including viewing other people's proven 2.3T maps who have made big power and not damaged anything. I made 14 dyno pulls this month while changing the timing map EVERY run to try to gather as much knowledge as possible about how much timing the engine wanted. Scott just tries to copy an LA3 timing map, though he'd never actually seen one until I sent him a picture of an LA3 timing table two days ago to help show him his timing table is fubar. He was just going off of what other people told him (incorrectly). Why don't you ask Scott where his timing "knowledge" comes from because when I asked him on the phone, he had no answer other than "that's what John told me the LA3 does". No timing map theory, no dyno testing, nothing. Building a Megasquirt and Tuning a Megasquirt are two completely different things. You can be very good at one and it means nothing about your knowledge of the other.
With that said, you can't just throw timing at it down low to make up for an oversized turbo/spooling issue. The turbo will spool the fastest when the engine is making the most hp (with ideal timing), not by just throwing a ton of timing at it and hoping it lives.
Here is another hint, of all of the guys who dyno'd at Matt's gathering, the guy who made the most hp without nitrous was running the least amount of timing. The second most hp pull also had low timing (similar to the highest hp car) but lost hp when he turned up the timing. He's since found it runs better with 3-4 degrees less than he was running on the dyno (which is WAY less than your map is commanding).
You can email them but I'm not going to tune it "for you". It will give me an idea where the tune is now though.
What's the use of having a megasquirt system if you don't know how to use it? I'd rather show you how to tune it yourself then tune it for you. If you're not interested in learning to do it yourself, let me know so I don't waste my time.
