installed new whipple 2.9

Just got my whipple 2.9 installed and running last night. I purchased directly from whipple and did the entire install in my garage in about 24hrs spread out over three days. The kit is the best put together kit I have ever seen. Fit and finish is second to none. Packaging was so good it took an hour just to tear all the foam off. Only small complaint is the instructions while very detailed have not been totally vetted for the 2014 srt. Some things were completely different and a few things just not there. They definitely need a revamp for the new SRT. However everything was there and worked with the cutting of a few hoses and swapping one fitting. Also want to give props to Jeff at whipple. He was a big help on the few little issues that came up.

Re: installed new whipple 2.9

So far it is running like a scalded dog. tranny cant always find a good shift point at partial throttle because the power throws it off a bit. paddle shifting is furious though. I love it. Also wheel spin on either the front pass or rear pass side is spontaneous and could happen at any speed below 60 when you gas it. This is an issue unless you tractions control turned off.

Re: installed new whipple 2.9

That is pretty awesome!
I take it you got the Whipple tune for it too? Shouldn't that help with the shift points?
I would love a supercharged Jeep! Enjoy.

Re: installed new whipple 2.9

Re: installed new whipple 2.9

Can you log the car?

I'd be interested in seeing a log of ignition timing, intake air temp, knock retard, lambda, etc.

Congrats on the install! How much boost does this kit run?

Re: installed new whipple 2.9

I'm running the same setup in my 2015. It makes 8.5 PSI of boost unless temps get well below 0c...where it will climb to 9 PSI. You have to turn traction control off in Auto mode or wheelspin will close the throttle under WOT, and you do get plenty of wheelspin.

Moving to sport mode rids the issue.

Tranny has some issues in higher gears trying to upshift...

We dialed the timing back and used very mild AFR tuning...and she makes a very safe 580 WHP. She has a good 70 left in her if I want to forge...

Did you swap your ECU to a 2014? Or did someone finally jailbreak 2015?

Re: installed new whipple 2.9

I wish. We had to swap out to a 2014...and I have had some issues since.

UConnect handsfree had perfect noise cancellation and outstanding audio quality, but now sucks horribly. I can't understand why this changed, because my impression was that no part of the UConnect has anything to do with the ECU, but obviously, there is a link somewhere.

The tuner built the tune entirely from scratch...which took a few days.

We have to go back and tune more - there is quite a bit of surging and power delivery needs to be evened out, but she delivers a ton of power and kicks like a mule!

Transmission needs some tuning as well...there are issues there too.

Slips into sport mode on its own while it indicates Auto mode on the dial, but Sport mode on the cluster.
