The mixtrim test has shown that your tune is way lean in some areas, especially the water and crank maps. The pump settings are probably all wrong too since you say the engine responds so much better.

I wouldn't recommend you drive this car under boost until the map is sorted out.

Unfortunately the Microtech really provides no way of sharing a useful datalog so I also agree with the suggestion of finding a competent local tuner.

Well the issue I have is there is no one besides my friend that is close to get this car tune with the microtech. what my friend does is he looks at a tune that he copy from a guy in Puerto Rico, and then give % base on that tune, in other words he is guessing. I said the car was tooo rich and that was the problem it will not start, so is the opposite. Lets see what I can figure out. Thanks for the help. I'll put the mixtrim back to 0%. So I call my friend up and he told me he took as much fuel off the water and crank thinking it was too rich. So what numbers you recommend to get the water and crank the right fuel to get it started in the morning.

The problem is gt it sounds like you have an expensive and powerful setup with a hack tune in it.
We can get it going but you shouldnt trust that tune at all as its nothing like a usual microtech map.
If you cant go to a pro (which is what it really needs) look at loading the basemap stickied at the top of the page and making adjustments for injector differences and porting.
To get you going for the moment make the following changes
these figures will only suit OPs tune not any others

Water
24c +25%
31c +20%
38c +15%
46c +10%
60c +5%

Crank
11c +17%
24c +15%
31c +10%
38c +5%

Crank obviously is for starting
Water is to keep it running
So you can make 5% adjustments to the maps to get it running.

Did not start at all with the new numbers. I even went to the Mix trim and gave it 20%, nothing, gave it another 5% still nothing. I'm about to put a match at this thing. Temperature was at 22*C. If I keep trying it drops the voltage to 10.8. So tired of charging batteries and trying to get it to fire in the mornings. But what I cannot understand, why 3 hrs later it fires right up???

No tuners at all in your area? You can try a post in your regional forum to see if there is someone available.

You don't necessarily need a Microtech tuner. Just a tuner. Any decent tuner will be able to tune any ECU because the principle is the same. Just some swearing as they look for stuff in the software, and in the case of Microtech, find out it's not there.

try mixtrim -5%,-10% etc as it may be too rich with the new numbers.
If that doesnt work try +5%,+10%
If still no go take out the new numbers and add the 20% mixtrim so we are back to where it starts and take note of the number before As on the handset.
This is the number it needs to start after all corrections.
Check it starts.
If it does put the above numbers in and adjust crank map until you get the same starting As number.
Pretty sure Elliot from turblown can do a remote tune for you if you find a dyno.

Hi guys, well I was talking to a friend of mine that likes to work on car computers. I told him what the car was doing not been able to fire up in the mornings. Then he ask me will it start in the afternoon when is warm or hot outside? And I said yes. So he told me not to drive the car for about three days so it can be completely cold. Then told me to get a heat gun and warm the computer, Microtech. So today I did that this morning, warm up the computer until I felt it pretty warm. So I crank the car and it tried, gave a couple of seconds tried again, almost. Tried again and wala!! It fire up??? Sooo, that tells me there is something wrong with the computer or mother board inside. So you guys ever had this issue?

It could be. Hadn't considered a problem with the ECU, only with the tune.

The test would be to try it a few more times (just don't overheat the ECU) and see if the fix is consistent. Another option is that with the car running on a warm day, cool down the ECU with electronics cooling spray. If it fails you have found an issue.

I tried it today stone cold. Did not fire. I warm up the ECU not hot just warm, and sure enough, it fire up.

Yes put back to zero and add the fuel on the water table. The 30c put on about 30% then ramp down to 0% at 68c
