That's not a bad point but I know for sure i have no boost least currently. That very well could change over time, too.

It's tuning related due to the elevation and the BMS PI flash being a one size fits all flash that doesn't work often very well.

Ive hired Trebila to help me out since it's that annoying and I can't figure it out myself.

Ahh, yeah. ProTunes FTW.

Roger sold to me without a business license.

he's chinese, he sells to basically anything with a couple of bucks to rub together haha.
I got some new O rings from the local seal shop because the supplied ones looked a little cheap.

Also having no dramas so far. Haven't fired the car up at all, but hey, no dramas ^_^

Hey don't blame this mess on our base maps. :) The JB4 PI mapping and BEF is doing exactly what it's supposed to do. Your PI signal from the controller to the JB4 verifying proper injection is solid and as a result high fuel pressure is holding steady. Fuel trims are within range. Everything points to the correct PI volume being injected. If you do need to adjust the PI volume for any reason or to experiment just raise or lower the by RPM adjustment levels on the user adjustment page.

The problem I see with this car is unexpected timing drops for the boost/power/fuel being used. And the mystery sputter you seem to have on spool. And as to the cause of those issues I'm not sure yet. You need to experiment to find the cause or as you've done hire a tuner to dig in to the car for more personalized assistance. As a first step I'd detune the car until you get consistent timing performance and then work from there. :cool:

Another idea is to disable the BEF hybrid spool mode, maybe one of the VANOS changes is causing problems with this manifold. Easy to test! As I suggested via email since you are basically developing/testing this setup get yourself familiar with TunerPro to make those simple changes. It's really easy stuff. You can change it faster than you can do a log to verify if it worked.

This is a good insight, we had 3 of the Orings start to fail after only the 5 dyno runs,

For those using a JB4 expect a safety mode = 4 failure if this happens to you. A bank to bank fuel trim variance of more than 15% for more than 1 second under full throttle. I've seen it come up a couple times lately with customers not knowing what safety mode = 4 was until they asked. As it's a new one.

Good to know terry! Thank you. I'll keep that in mind when I get it going again and on the dyno.

Except us ST guys will get MAP 0. ;)

Terry to be clear without your products I wouldn't be the loyal customer I am. I hired a tuner to assist me since my tunerpro knowledge is minimal. But the issues I'm having I assume are related to elevation and overall needing some timing changes for the setup I run.

All in all, your base flash maps worked great until I added PI. That being said it could be other factors aside from the DME flash. But to have a custom flash built for my goals will likely help with the issues and bring improvements from the base flash. So to be very clear your work is valuable for folks who aren't having issues. Likely 95% of the tuners who have various setups.

I'm the first person to advocate your product and service with the rise of MHD people ditching their JB4. The safeties built in plus the support are primary reasons why I've spent $1K+ on BMS products :)

No worries I just didn't want someone to read this six months after the fact and determine our base maps are not awesome. Because I think they are. :) That said always looking to improve. I'll stay tuned to see how you resolve the issue and then incorporate that logic in to our base mapping if possible.

I have gaskets in house that work, as we use a wide variety of orings here. I honestly wont be running this manifold, its not worth it for the hassle to just get the charge pipe off. If anyone wants it, and doesn't mind not having PI, I will sell it for $350 with the new gaskets, and everything that came with it. It was literally ran for 5 pulls on the dyno, and removed.

Tony could you give more info on the gaskets? Ideally so we may optionally purchase these for the PI?

Im running the orings that came with the manifold and with 22psi of boost have had no issue but its also like 40 degrees in Denver right now so when summer hits i may find these melt possibly.

To be perfectly honest with you, I have no idea what these are from, we just have shit load of O-rings laying around from different things, I went through our "Oring box" and found 6 that worked better than the ones provided. My guess is they one provided are Buena-N which is why they are soft, and blowing out.

Alright guys due to Chinese New Year we are delayed on the group buy. We will likely start this week anyways with the understanding that they are going to take 3-5 weeks for delivery. But the value is well worth it.

On the topic of o-rings i have run my car a dozen times on 24psi without issue or boost leaks. (did a smoke test to confirm).

So i am wondering if the VTT test car was too badass and blowing these gaskets out. ;)

So, im in for a group buy but i would really like to know when Tony plans on posting results of his manifold test. I may have missed it but i didnt see anything. I'm willing to bet the manifold that wins your mani battle is going to be much more expensive than the one we are talking about here. Since i am on a budget i will probably going with this one but i would really like to know what the best on the market is so i can compare. Also, Tony, if you dont mind me asking i am curious, besides the charge pipe being hard to get off, does this mani perform well? I dont mean to call out flaws when obviously people are looking to purchase this manifold but i feel the need to know your opinion since you do have a high HP build and know what youre talking about.
