SLP Predator problem
I just got my SLP Predator for my 07 C6 A6.
When I plugged it in, it told me "ECU voltage wrong"
I tried it a number of times but got the same error and I time it told me
I had the wrong unit for the car. Presumably it never saved my stock tune or loaded anything.
Now when I start the car, the fuel guage is on 0. The DIC tells me I need to service the fuel system and the check engine kight is on.
SLP is closed for the night so I can't talk to them until tomorrow.
Does anyone have any idea what I may have done wrong?

well, to fix your car before trying anything else, disconnect the negative battery cable for about 15-20 minutes.
reconnect it, then fire her up... should be fine - besides having to re-set the radio, compass, etc etc.
then post your issue on Diablosport's GM forum...

Thanks for the good advice. I did that and I now appear to be back to normal.(which will make for better sleeping tonight!)
I will call SLP in the morning and see if they know what the problem may be before I post anything to the forum. It seems like it should
be very straightforward to install the tune, but I am not ruling out operator error yet. Hopefully I will be able to figure it out and not turn my C6 into an expensive paperweight.

I just talked to Joey at SLP and he said that the only way I can get that message is if the battery charge is low. He suggested I put it on a trickle charger and try it while the battery is being charged.
I drive the car almost every day so it seems like the battery should not be low, but I'll give it a try and let everyone following this thread know if that works.

Also be sure there is nothing in the car drawing voltage when tuning.

Mike L,
Thanks for the info.
I did make sure eveything was shot off before I started.
How would I go about getting the calibration updates you mentioned? is this
a warranty issue?
I see you work for Diablo. Will it hurt anything if I have my 2 amp charger on the battery when I load the tune?
Thanks!!

Trickle charger is a good idea in this case, and will not hurt anything.
Thanks

Round 2 - Still no success.
I hooked up my charger set on 2 amps. Pulled the 2 fuses. Set the parking brake and closed the doors. Plugged in the Predator and turned
on Accessory mode.
The Predator booted and I selected Install Tune. After about 4 seconds it came back with the error message "unable to verify ECU voltage for programming". I tried it twice with the same results.
Once again, after unhooking everything the gas gauge didn't work and I got the DIC message to service the fuel system, although no Check Engine light. After unhooking the battery, letting it sit for 15 minutes, then reconnecting it, everything appears to be back to normal.
FWIW, the only 2 things I had to do were reset the clock and re-index the windows after unhooking the battery. Radio was still set.
I am now thinking that the Predator has something wrong with it, unless anyone can see anything I'm doing wrong. I'll call SLP tomorrow and see if they have any thoughts on what the problem is.

Se e what SLP says, and if necessary, fill out an RMA request on our website and send the tool in to be repaired or replaced.
Thanks

Mike L;
I talked to Joey this morning and he asked me to check the revision level of the software in the unit. I think he said R06 is what it should be. I can't do that until
tomorrow morning. He said the software may need to be re-flashed.
I'll keep the thread updated.
Thanks for your support.

It looks like my Predator had an old version of software on it. It was
V8R03. I've sent it back to SLP and should get it back next week.
Hopefully I will then be able to install the tune. It doesn't seem like a big piece of plastic with 6 buttons on it should be that difficult. If I am then unable to install it, I will immediately put in a application to get on "Are you smarter than a fifth-grader".
I'll keep the thread posted.

success - I think
I got the updated Predator back from SLP. It says V8R06 now.
I pulled the fuses and started installing it, After booting up,
it said "unsupported vehicle", but I hit "continue" and it then
proceeded like I would have expected it to.
First it loaded my stock tune onto the Predator, and then I selected
"Factory Tune" and it loaded that tune OK. Both took about 1 minute.
After loading, the car started and ran fine, although I didn't run it
enough to notice any SOTP difference. Its also in the 80's and humid out, so not exactly ideal conditions.
I would feel better had I not gotten that "unsupported vehicle" message.
Does anyone with any Predator experience know why I might have gotten that message? I am assuming everything is OK now.
I am also interested in knowing if I can just plug it into the OBD port with the vehicle turned off and not on accessory and just play around with it with out hurting anything. Any comments on that are also appreciated.
Thanks to all!!

you need to select one of the performance tunes and install one of those.

I just talked to Joey at SLP and he confirmed what you said. I need to load the
435 HP tune, even though I don't have the intake and exhaust. He said I
should re-store the Back-up tune, which is my original; and then load the 435.
He also said the "unsupported vehicle" message didn't mean there was a
problem.
ALK
I should be able to give you a good update tomorrow. I'm planning on going to
Union Grove Dragaway tonight to see what the difference is. I ran it for the first
time on September 5 and my best time was 13.09 at about 109 MPH. I'll let
you know how it turns out. The weather today is much cooler and dryer (before
was in the 70's with 75% humidity) so I would expect that to help some. I'm interested in how it turns out also.

Thanks for the info. I think what I will do is take it down and run it once with the current tune, which is basically just the stock tune, and then I'll load the 435 tune
and run it again. That should give me a really good comparison.
Since I'm a little gun-shy after my first issues, if for some reason it fails to load the 435 tune, is there any danger I'll be stranded with a car that wont run? If there is any possibility of that, I'll make the change in my garage and then go down. It just
seems like a good opportunity to find out exactly what the tune does.
