Called Tech support and Mike helped me though everything!! Turns out I had to switch the verification off on the tuner so it could save the original backup. Thanks Mike. #1

Reinstalled new revision (v.9r05) tried to install tune again. After attept to save Original Backup while tying to install performance tune it came up with "Unable to save Original Backup (-30). No matter what tune I try to install it comes up with the same thing. After trying to save original ...

U7146, v.9r04, Ford, Mustang, V6 - I updated to v.9r05 without restoring the original tune first. Went to modify some stuff on my car and it restored the backup file to the car. Tried to install performance tune and it tries to read the file from the car and it gives me a code after 2 attempts to ...

Predator u7146, Ford Mustang V6 2002... I am going from the stock 3.25 gear ratio to 4.10 and need to know what weight/thickness gear oil is recommended? I know that 80w-90 is what it takes on a stock 3.25 gear and have heard that 75w-140 is a good weight to use when going to 4.10. Thanks in advance ...

If you are using usb to serial to connect the tuner to the computer this should pop up under Ports (Comm and LPT) - "Prolific Usb-to-Serial Comm Port (COM3)". Right click on it and press properties, then on Port Settings set bits per seconds to 115200. Then on DS Downloader remove auto connect on ...

Are you using usb to serial, or another type of connection to connect the tuner to your computer?

If you live in a area that is cold there will probably be no need to replace the thermostat. On the other hand if the climate you live in is hot like where I am from, 104* day/ 80* night, then a stat would be good. So it depends on the climate in your area if you should go with a stat or not. A 180 ...

I am not trying to throw my maf curve off to much, so a 73 should give me enough without going for a dyno tune or spending crazy jack on a a/f meter. Going from 550 cfm to 700cfm wont stress the computer out too much, and I should see some noticable gains. I am only doing basic stuff here.

I think that the diablo tune will only help your car with the mods you have installed. Your car may run a little hotter so you might want to replace your stock thermostat with a 180* stat, so you run a little cooler but stay at a good burn temperature.

Just an update on what I have done. I replaced the 192* factory t-stat and installed a 180* instead of a 160* stat, you dont want to run to cool so you can get a better ignition. Also turned down all fan settings 12*, which was the differance between the existing stat and the new one. Another ...

Have you installed the Diablo tune. If so what problems are you having with it?

Got no answer for my question, but I went ahead and installed newest revision to the predator, and installed the diablo tune on my ride. It felt alot better then the factory ford tune, but I felt with all the bolt on upgrades that I had installed on my car it should perform better. Did some research ...

Thanks for the link. I will try the book.

Why not sell a book with more info on how to tune a car with the predator with as many differant situations that you can fit in it? Maybe it would end the need for repeated questions that I have been reading in these forums, and I am sure many people would be interested in it. All I read is "get ...
