Two Tune Comparison File Review

[fiero88pro]

Hi all. I have two separate tunes that were done using two separate companies and was wondering if anyone would take a look and give feedback regarding which one you think is the better tune. I've noticed on one tune the knock sensors are disabled and the other is enabled with MIL light on 2nd. Do you recommend they be disabled? Otherwide just take a look at each file and let me know your thoughts. 1988 Fiero with 3800 SC, 4t65E trans w spring shift kit. Engine has 1x blower cam, headers, ported heads, ported blower, 3.4 pulley, motor has been balanced, 3 inch exhaust w flowmaster muffler. Thanks!

KR should never be disabled. Make them react to a KR event faster if you like, but disable them... no way bud, this is before I even open the files

I figured as much but wanted to check with others as well. I have turned them back on. Thanks. If you notice anything else let me know. Just trying to figure out what parts of each tune are best. Thanks.

Didnt look at tunes but personally I would stay away from the one that disabled the knock sensor, if they did that they most likely f@#ked everything up.

Shift points need to be fixed in there as well. Your WOT shift and Normal shift at 100% TPS should match.
Shift pressure is pretty low and shift speed could be droped a little too. The shift pressure caped at 96 is a good thing, leave that where it is
You have performance Shift button in your car? If so, increase the performance table and leave the normal alone if desired. if you do not have the button, then adjust the normal one up. A great way to do this one I got from Russ a few years back... clear out the shift pressure table, place 0 in the first column and 60 in the last. Interpolate the table and you should see a rise from 0 in the first to 60 in the last. Copy that table, then undo changes so the original table is back. Then paste special add... give that a try and see how it feels

ok thanks
I looked at the wot and normal shift tables Do i change them all to match upshift and down shift how much should i drop the shift speed do you have a table that you can copy Yes i have a preformance shift button i would like to have it set for race and normal for cruseing but i want positive shift on both just more harsh on performance i got this trans tune off the form i had a issue withe the torq conveter lock out i only changed the tables in the auto shift speed section but now i have a copy of the complete tune and change every thing in the transmission sections to match i have not down loaded this into the car yet i want to make sure it is good to go before i drive it The transmission tune before this one i was stock it was really slow shifting Is there a way i can make my overdrive not engage intell after 65 mph The transmission is a 4t65e out of a 2003 grand prix gt pcm is a 2003 also
once i get it to shift like i want we can look at the engine tune engine runs good but i thing need some adjusting
