Power with latest V4 map

The car feels quite OK and has a good powerband. 3rd gear pull shown below.
Ignore the STD and SAE readings, I didn't put in data for temp etc. so it is just the Actual curve that is of interest. The car has never run better than with this map, which is 4-8.

It is done by data from the Racelogic unit and a MS Excel application. It is an enhanced version of this http://forum.e46fanatics.com/showthread.php?t=736883

I have now tested it in cars that have been recently dynoed on conventional dyno's, and the outcome is very similar. It is a great tuning tool.

What suprices me is that you get all that power with stock intake and exhaust.

Yes, 70/30 meth. The intake is a Mr. 5 type intake with an extra 3" cone filter behind driver side inner-fender. The stock catback seems to work considering the engine now produces about 150 hp over stock.

What were your user adjustable settings? Do you ever run a procede log the same time you run your racelogic? Would be cool to see both sets of data for the same points in time.

I always run Procede logs when testing a new setting, and archive the results. I'm currently testing UT 75-80 and IC 50-20 on map 2. Map 1 is UT 55% and 80% IC. The boost is a bit high now on map 2, but there is a pair of replacement turbos to throw in if and when these are cooked. I do not publish logs on a non-public beta version. The developer whether it is Vishnu or BMS must get the possibility to finish a release before presenting data that may be used against them by some.

No I don't, do you know how to check this? It is a MD80, but I don't know the SW release.

the dealer can do a print out of the ECU version for you just from doing a key reading. that's the only simple way that i know of.

I took the car out and the car with the progressive meth on 4-8 is a ANI-MAL! Raw but yet smooth in one sentence!
