Hey guys,
I installed a Stillen S/C on my truck a few weeks ago. After installing the kit I put about 500 miles on it to allow the ecu to adjust, then I hooked up my wideband and scantool to it. The fuel trims are horrible and WOT AFR was around 14.5:1 (way too lean for forced induction). I'm also having some pinging issues (93 octane). With no way of retarding the timing and adjusting the map on the road I'm having to stay out of the throttle for now.

Anyway, I'll stop complaining and get to the point. Do any of yall know of a company that makes a good piggyback (like splitsecond) for the titan with self- tuning capabiliy? (Fuel mapping, open and closed loop, and timing retard) I've been looking for a while and I haven't really found anything.
I'd really like to toss the Chip that came with the S/C, install a good piggyback and retune it myself.

Don't get me wrong guys, I love forced induction and wouldn't have it anyother way. This will be the fourth vehicle that I've installed a supercharger on and once this one is done right I'm sure that I'll enjoy it as much as I have the others.

Thanks in advance,
Pritch

Ah......the ill tuned Stillen piggyback issue has reared it's ugly head again. There are no "good" piggy-back units for the Titan. You will need to contact [email protected] Stillen and they will probably have to retune for your truck. I wouldnt be doing any more WOT runs anytime soon.

Good luck!

I'm not aware of ANY piggyback for the Titan that allows you to custom tune. The only one that allows that is the reflash from UpRev. The Osiris software they do for us. I don't know how well it works with the SC though. Give them a call. They're great guys.

Stillen wont have anything to do with Uprev.......kyle made that clear in another post.

 

[Carbeaux]

But will the UpRev stuff let him do the custom tuning he wants? That's the question. The Stillen piggyback certainly won't.

 

[roy365]

No.....Uprev can't/won't attempt to override a piggy back unit. And if you do take off the Stillen VK pro and use Uprev say bye bye to any warranty.

 

[roy365]

You can use their Cypher software to monitor and clear codes, but nothing in the form of tuneability.

I would contact [email protected] right away. He will probably have to over night you a new tune so your truck is safe.

:dunno: Since I was reading your thread out of curiosity, I thought I'd share a prospective solution. I don't have any personal experience with forced induction or this particular company or their electronic engine management systems. :hungry: Check it out and let me know if my suggestion helps. :clap:

Send your data logs to Kyle ASAP. It might be the tune or the wiring may be wrong in your truck.

Listen to Qship, he's been to the rodeo more than a couple times and been thrown by this bull many times.

With all these potential troubles, this really makes me not want to supercharge my truck at all....

Hey guys, thanks for your replies. I'll give Stillen a call and see if they can get me closer to where I want to be, or at least make it safer to drive. But the problem with a preset tune is that there is no way to come up with a map that works good for every truck. You have to factor in time of year (temperature) and elevation. With a stand alone unit and proper tools, you can create a map for summer, mild weather, and winter months. Then you know that you've have a perfect tune year around. Also, if any of you are like me and can't leave well enough alone, it would enable us to go to a smaller pulley without tearing anything up.

Stillen isn't the only company that comes with a non adjustable chip. Rouch, Kenne Bell and most other kits come this way. The differance is that there are cappable piggybacks available for most makes of cars and trucks for under $500, just not a Nissan Titan.

We need someone to come up with an online performance store just for the Titan, like Under Dog Racing Development does for Toyota trucks. Till then I'll check with the guys at split second and see if they can come up with an application for us. I've used them with Toyotas and there units have proven to be very reliable. (I've had one installed on my Tacoma for over 4 years now with no problems.)

Anyway, thanks again guys, and let me know if yall find out anything.
