I want a DiabLew tune. I had johan make me a 93 tune for the hard shifting, what else could you do to add to it.

I found the email that johan sent me and he sent an 87 and 93 tune.

I had to get a custom tune to fix the hard shifting of the transmission from Johan a while back and he sent me a 93 oct tune. If I want to run 87, how would I adjust the settings to control the knock retard? Do I lower the timing and monitor how much KR there is, or is there a set amount to lower to ...

On one of my previous threads someone chimned in about what the changes actually were. If you lower the shift pressures all the way to -25% it will help but still shift a little hard. The best way is to have mikel get you a custom tune so you can then set the shift the way that you want it.

WOT means wide open throttle. I have the same tuner for my truck and right underneath wot pressure should be the part throttle settings.

It means to the top.

I have a custom tune to help the rough shifting and I got my LTFT's dialed in, now the truck runs great. I have not adjusted the PE cuz I do not have a wideband to monitor the setings. I was reading about some of the adjustments that other members have made and someone said that they maxed out the ...

There is a problem with some of the 99 - 02 GM trucks that when you upload any tune it will shift very hard after going wot. I had the same problem. Install the tune and the truck shifted great untill I went wot then it would just slam into gear and the only way to make it shift smooth again would ...

Hey mikel I sent you the backup file or should I send it to Johan?

I have a question about the 93 oct tune. A while back Johan had sent me a custom 87 oct tune to fix my hard tranny shifting. I have been using this custom tune with no problems so far. I would like to try the 93 tune that came with the unit, but I was wondering if the tranny will shift hard in this ...

I have a 2000 GMC Sierra 5.3l auto and under full throttle the tranny shifts very hard. I turned the pressure on wide open throttle to -25% and also on part throttle. I also changed the shift time to 12% slower and when you drive around normally or part throttle it shifts very smooth. Every time ...

I figured it out. Iam so dumb. I did not save the file to the predator, so I saved it and now it is working. DOH!!!!!!!!

Yes I am using the 99-02 interface and I can save the current file to my pc. It is not on the desktop but in a folder in the c drive. The problem is that it will save the current backup file, but every time that I try to upload it to the predator I choose the file and it says invalid file. I name ...

I have my predator hooked up and I saved the vehicle backup file. I keep trying to backup vehicle current file, which it does, but when I try to upload to the handheld it says Invalid File Format. Can you only save the original stock tune? I would like to save the changes on the 87 tune that I made ...
