I have always disliked the delay in the pedal on my 2008. I have compared it to a 2006 and there is a very different feel. Has anyone tried this?

I dont think ive heard of anyone using that. Seems kind of expensive at $300 when you can get a programmer and have more features.

[p@55w0rd]

Yes it is expensive... But I noticed the throttle delay from day 1. I even had a chance to drive 2 other XK pre throttle by wire and there is a significant difference, especially when you goose the throttle on a obstacle. Superchips does not correct for this to my knowledge.

[Matt]

I thought the superchips did reduce throttle delay... its been a while so id have to look back into it.

But the sprint booster says it cant be used with aftermarket programmers. So to use it you'd have to give up your other programming capabilities.

I wouldn't advise "stacking" electronic throttle control devices; thats a serious safety issue.

The DiabloInTune eliminates throttle delay and has many adjustable parameters which I strongly suggest getting for similar money..

I personally would never spend $300 in this. Get a nice tuner and ported tb and you will get way better throttle response and be able to tune at the same time

I have the inTune as well. It allows you to boost the throttle response. I run it at +18% if memory serves. Much more than that and you won't be able to get a gentle response.

What happened to the fellow that was offering to hand port TBs for what I thought was a good deal. I can't remember if was here or the jeepcommander board, but he was waiting for a shipment of 4 tbs to get started.........and the......... I don't know what happened.

Can you do a transmission tune with the Diablo?

[06JeepXKHEMI]

Yes, check sig.. There are a lot of parameters that can be adjusted, keep in mind you will be changing how it drives.. With the throttle boast and transmission tune its not civilized as a stock XK, it will shift harder, quicker and throttle will be touchy based on how much you adjust it.. There are times I chirp 2nd gear on dry pavement, havent tried with the MTRs but with the BFGs I could make them bark pretty good

[thance]

With the iTune you can adjust shift points, but not firmness (that I am aware of). I have a separate module that plugs into the side of the tranny and makes it think it should boost pressure (firmness).

[06JeepXKHEMI]

The performance transmission tunes states it will make a quicker shift, thus feeling firmer grabbing the gear quicker..

[thance]

Where did you get the performance trans tune?

Mine does not mention transmission in any of the tune names, however I can change shift points in adjustable parameters.

As everyone else is saying, if your going to spend that type of money get a programer.

I'm running the Superchips Flaspaq along with an extra ground for the TB. The Flashpaq does come with in the tunes programming to reduce throttle delay.

I read somewhere, I believe on this fourm about grounding the TB helps with reducing delay. I did it about a year now and have not had an reason to undo it.

Also the Flashpaq has Trans programming (Paid Option $100 on top of the Flashpaq)

[06JeepXKHEMI]

I will have to go back in and look exactly where it is, IIRC It's under the octane tunes.. It allows adjustment for recline, shift point, How long to hold that gear based on %of throttle. So it will hold 1st gear if I'm 60% throttle or above and 2nd 40% same with 3rd. There are other adjustments to that I didn't bother with but it helps with the sloppy shifts from factory..
