I am using a 7140 that came with my Paxton Novi Blower. I just added the Intercooler kit which came with the Mafia. Is there any issues using a IAT relocation kit in conjunction with the Mafia.

I am using custom tunes since the 7140 doesnt have the oprtions for Delete Plates in the canned tunes for ...

I am interested in the CMR as well, a watered down version that allows general changes would be Great, and also better data logging. I have been trying to find a 90 degree adapter for the predator so when I am doing data logging the plug isnt in the way of my clutch leg.

I have been very happy ...

Well I spent the day at Dez Racing in Seekonk. Mike does all my tuning and it had all of us stumped. We finally figured out we were looking at the wrong end. Everything up top was perfect but it wasnt pushing it out the back. Both Cats were clogged up. Runs like a champ now and with the new 3.90 ...

I have just been logging to the predator and logging all parameters .. Here is a log from a drive around the block, as soon as it starts making boost it starts bogging and if you hold it, it will start knocking .. Got me totally stumped.

Well I think I have isolated down to a lack of fuel when it gets into boost.. So I am guessing the crappy little piggy back pump you get with the Novi kit has gone belly up.. I'll post my findings later today.

Ok here is a log file, not very long. Just revved it up a few times after driving it for a while. I revved it till it pinged a couple times. Not sure if you can figure anything out from this or not.

No trouble codes at all, I do have a narrow band guage hooked up off the left top O2 sensor but it hasnt been an issue. FRP which sensor is that ??

Bad plugs?
Vacuum leak?
Loose coupler somewhere?
Burnt wire?

Changed the plugs, still pulling good vacuum on the guage and idles fine, checked all the connections anyway, checked all the wires and connectors and everything seems just fine.

Thought it might have been a tank of bad gas, but ...

This is an 07 GT/CS

OK here is the deal. Went to work Friday, filled up with 93. Didnt notice any problems and car has been running Great. I have a Paxton Novi 1200 and Mike at Dez Racing tuned it. Puts down 412 rwhk with 374 tq and pulls real hard.

Went to lunch and spark knock city when ya get ...

You are always better off getting a good Dyno tune. There are alot of e-mail tuners out there that can send you a tune, but they will only be close, if you want it tuned to perfection, go to a good dyno tuner.

This file is fine. It is smaller because it is compressed to contain only the changes specific to the custom tune.

Thanks John, I was thinking along those lines but wasnt sure.

One thing I would love to see in a future software upgrade would be a menu driven download that would allow you to ...

I just did the upgrade on my vr7140, I had to wait until I got my custom Paxton Tune from my Tuner. It all went well after I used a different computer to do the update. I reinstalled my custom tune and all is well.

Now I attempted to test the last tune written download to my computer and here is ...

Disregard ... I tried the update on my other laptop with a usb to serial dongle and it worked, go figure ..

Thanks anyway, but I fixed it hehehehe

Just tried to update the CROM file on my VR7140 and it loads Ok but the Predator never reboots, just sits saying Intstalling Bootloader. Let it sit for about 20 minutes and nothing. Unplugged it and let it boot and it says Corrupt need to reinstall.

Need some help here as I am dead in the water ...

If I update my predator with a new crom file will I loose my custom tunes that are in it ??

Thanks
