How was the tuning? I have a sprintex on my 03 but it has been at the tuner for ages. Seems like he’s having a tough time getting it going. Any help would be appreciated.
 
It was quite a learning experience, if you haven't messed with a jtec ecu than it's going to give any tuner a hard time. I had two different tuners attempt to tune it and I wasn't even able to idle it in my driveway. I would recommend using a gm 2 bar map sensor and scale it using hp tuners. You need to take screenshots and logs of your factory tune and where it sits at idle. Than set the map scalar to 190 and you'll see the idle sits higher in the fuel map now you'll have to adjust it and set the idle air fuels and than start with mid and wide open throttle. I used the factory map scale setting and it would only compensate for 5-6psi of of boosting when I was hitting 12psi. It depends on your boost level you can trick the ecu into running it without adjust the map scalar but I had a meth injection kit so tuning was more forgiving.
 
I see. I’m thinking I’m gonna have to pay someone who knows the Jtec then…
 
I believe Flynn ryan does tuning via email but it's expensive. The tune i priced out was almost $1700.
 
I had him try to tune my jeep years ago and that was a failure. Tried the SCT and he couldn’t get it to work multiple times

The SCT didn't allow a lot of areas to be addressed but now that HPTuners supports the older Jeeps he seems to have better luck. And he knows our vehicles too.

WOW how did you get to so much? I have a custom tune for the Hemi in my TJ since it's got aftermarket parts and it was $700 but I already had the MPVI2+.
 
So I had a 4.0 that was bored. 030 over , stage 2 race head with port and polish over sized valves and around 12-13psi. If you go on the website it said it cost around 1700. I heard he stopped doing jeep 4.0 tuning but who knows. I mean I know my jeep wasn't professional tuned but it worked for me

Have you spoken to Ryan lately?

He just tuned my Hemi this fall.

As long as it works that is all that matters...

He'd taken a break from doing the JTEC stuff for a while but I think he's doing them again on a case by case bases. He did the Magnum V-8 I had in my Jeep about 2 years ago.

Doesn't hurt to reach out and ask... @Flyin' Ryan Performance are you doing the 4.0 anymore?

I have never "taken a break" from tuning JTEC. EVER. I just did a blown TJ yesterday. I took a brief hiatus when I was changing day jobs where I had someone tuning on my behalf, with oversight from me. Even then, we still did jtec tuning.
We have a disclaimer that all 96-98 JTEC tuning w/ HPtuners is at ones own risk , because the datalogging with those on HPTuners has been spotty at best. I can't blame someone being salty about spending 1500+ on a tuning suite only to discover they cannot datalog.

I don't know where some of these rumors come from...

@Matt84 , SCT did have some occasional issues with the Jeeps (mainly with datalogging). That has nothing to do with the service we provide. The issues seemed to be at random/specific to individual vehicle and not year, model, etc. We stopped selling SCT handhelds approx 18 months ago because of these sorts of issues. Since then, everything JTEC has has either been via hptuners, bench flash (which I use HPT on) , or SCT but customer has to source their own handheld. I cannot custom tune without datalogging. If there is anything you need, send me an email, ryan@frptuning.com with your order # and information and we will see it through. I would prefer to deal with order/customer specific issues in private discussion.

There has been HUGE, HUGE changes to the business in the last 2 years , guys, I hired staff, moved facilities, moved custom tuning to an appt-based basis to eliminate variance in tuning wait times, I went personally through approximately 16,000 emails to ensure everyone that may have tried to reach out to me got some sort of a response.
Outside of any period of time where I was out due to my wedding or the birth of my son, email turnaround times (outside of appts) has averaged 1-2 business days tops and if by some chance I am not able to be reached, there is staff available to speak to via email, phone, web chat.

We have been the gold standard for Chrysler/Jeep/Dodge late model engine management and we will only continue to be so.

Regarding the pricing... There's plenty of people that will swing and miss, for less. To run my business with brick and mortar, staff that are skilled and motivated, overhead, inventory (moreso for parts) , and all the ancillary stuff that comes with that, then deal with the precarious nature of tuning 20-30 year old vehicles that someone else built, sight unseen with precision, this is what it costs.
A device costs 400+ shipping, and credits cost 50.00 per unit. I stopped using AEM widebands because of failure rate, so you end up with a 400.00+ Ballanger wideband. So yes, it is very easy to end up with a "expensive" tuning arrangement because all of these items are critical to doing it properly.
If you can find someone with our kind of experience, let alone track record when it comes to tuning these platforms, and will do it for half the cost, by all means, I would understand anyone going the cheaper route.

The only thing more expensive than doing it, is doing it over. This is why our motto here is "Build it right, or build it twice"

Ryan

I'm sorry I thought I'd remembered you not tuning the JTEC for a while... But my memory SUCKS so who knows... And I don't mean to spread misinformation.

I have nothing but praise for the service I've gotten from FRP & YES i complained about the cost but as Ryan said what is your build worth? And do you want to have it done RIGHT?

I didn't know you'd had issues with the AEM widebands.

Don't I know this??? Freaking money pit..

Thanks for the reply
 
I also heard from a third party you took a break from tuning the jeep 4.0 engines. To be honest I Spent around $4000 on my build and dumping that much into a tune wasn't worth it for me personally, yes I'm sure you will do a 100% better job than I would and it would run flawlessly i was determined to figure it out myself and I did after studying and some trial and error. The jeep 4.0 crowd will barely spend $500 on used performance parts so expecting them to pay top dollar when it's one of the cheapest customer base around is well and issue. Also I only went off of the website with the links listed on their and it came out to a total of $1700 for a custom tune, that's almost half what it cost to do my build and almost into ls swap territory to get a properly tuned boosted jeep 4.0 just doesn't make financial sense. Hence I tuned it myself had a bunch of fun and learned some things and now I sold that home setup and I'm doing a ls swap because it's cheaper and alot more reliable .

The rumor mill runs deep. I've never taken a break from Jeep 4.0, or JTEC tuning. There's been short breaks where tuning was pulled (not Jeep , JTEC specific- but across the board) to manage workflow (finish existing projects), but we are talking 1-2 weeks, 30 days tops.
Dumping thousands into a 25-30 yr old vehicle (not looking down my nose- I have a Dakota RT that is stroked, turbocharged, and 8HP70 swapped) generally is not regarded as a financially astute decision.
We are catering to those who want the best. The best, comes at a price point that may not be agreeable to many. If this segment of the community didn't exist, we wouldn't be able to keep the lights on.
If I could slash tuning costs by half and still net customers that show up with mechanically sound vehicles, and I could deliver the same quality tuning/service expected out of me consistently, I would do it. I can't, so here we are.
There are many options out there for tuning/parts out there, not all of them are equal. I'm glad you got your stuff running well, the satisfaction of a job well done is part of what keeps me going after all this time.
