that looks like a partial run to me IF the mph shown is correct...

It was a little rich but it seemed to only be showing 14 psi of boost....is that close to what your boost gauge was showing?  The map sensor may need to be calibrated?

Prior you said you were running 17?

Given that I see no timing retard during the run, the fact that it is a slightly rich, and that you said you had 108 in the gas tank, I would probably raise the third gear timing from the default of 18 to about 24 degs....look at the chart in the instructions and select the setting that is close to 24.  If you have good traction, you can raise the first gear timing as well.

I would not suggest changing fueling unless I knew the mph and boost are being reported right

I see some other problems such as the reported voltage is too low but I don't know if it is reporting what is close to coming out of the alternator, or if it is a connection problem between the alternator and the ecm.  Also see some minor timing retard before lunch which makes me wonder about a bad motor mount or something rattling.

A lot of broken parts does not make you a racer; it makes you a slow learner.

I dont have a 3 bar map its only a 2 bar i have a two step thats y u see the retard timing the boost gauge fell so havnt been able to get a correct reading on that i did raise the 3-4 timhg to about 23 i got good traction we r only running 1/8 mile due to people hitting the wall track got to 144 degrees nd all the fast cars were blowing tires of the hit we r only running 8.40 to 1/8 at81.07 my junior dragster was faster than that. Did raise timing to about 22 degress on 1-2

I saw 14 on the pl display for two bar which is what I set it far...thought you said you had 17 the other day...anyway, you can raise the timing more...can add a pound of boost as well
