You mean people actually live in the Panhandle? LOL

I'm about an hour south of Tampa, never driven to the panhandle, but I'd imagine it's 5-6 hours from me to Pensacola. A real shame, cause I'd love that race. "

If you end up finding some logs, send them my way. I'm curious to see if the failures were really timeouts, the errors i mentioned or something else entirely.
Made this thread a while back, there's a screen shot of a typical log from most of the computers a few posts down. My 2007 failed with literally every Intel computer until Haswell 4th gens, but worked with 3 AMD based computers. Who knows. Regardless, still interested in a coding cable port.

" HAHA yes. Agreed. The MSD81 is like a supercomputer, even compared to an EVO ECU. I have DSMLink V3 in my DSM and do like that quit a bit, but it's certainly no MSD81 with a JB4.

I hear you though…

Edit: and I’m sure you’d agree that MSD81 is in another universe of nuance and intelligence than DSM ECUs. But your point still stands, for sure.

It's not that easy on any other platform unless you're running a real stand alone that will do the same things that the JB4 does for the BMW guys.

mjmarovi replied to the thread Renntech BMW N54 Flash Tuning, 100+ wheel horsepower.
" Ok...so power gains are similar to the JB4 or a Cobb with a protune. Maybe a little more power, but that's just being a little aggressive to get an extra ~20whp without doing other upgrades.
@Mike@Renntech I'll be honest that price does seem extremely high considering the Cobb Flash is $900 and offers a handheld that can be used for other features including datalogging. What do you offer in terms of re-flashing/tuning for additional upgrades and doing custom tuning depending on the location the vehicle will be used in?

See, basically what we are looking at is a the product of a very aggressive custom tune on one particular vehicle. So not only are those gains not going to be consistent using that same flash for other cars wherever they are, but it's not even safe or recommended.

I'm sure you have all of this thought out, but I am simply expressing concerns others would have as well. We just need more info, any new product especially from a company with a great reputation is going to catch some attention. The price really adds to attention because we would want to know what the advantages are. From the information you've posted so far...there are only disadvantages seen. The way it feels now is if I were to send my ECU in to you (major pain to do in itself plus additional costs) and have you flash it with some tune you got off of a test car, and send it back to me. How is that any better than buying a Cobb and using an Off The Shelf aggressive tune? Except for with the Cobb you can datalog some street pulls, and make adjustments yourself, or go to a Cobb pro-tuner in your area. Or, Pro-Tuning Freaks e-tune.

I'm sorry if it comes off as me being offensive, but I assure you I am doing nothing but trying to help and lay out all concerns and questions the majority of this platforms' users would have.

Thank you and looking forward to your response, "

" Just to clarify, the WB gauge is not the end all solution to not melting pistons. It's just a tool, that as of right now, no one in the BMW community uses. (almost no one, Chuck LOL). It may not be necessary for JB4 guys, but it can still be a piece of mind for those that don't mind an aftermarket gauge in their BMW. I personally didn't like the idea of gauges in my BMW LOL. but I wasn't pushing it to the ragged edge with a single turbo either. "

Second, if you really get a serious lean condition, you’ll have what maybe a second or so to react to it? I doubt folks would be able to back off in time if you suddenly leaned out like crazy. You’d have to be 100% focused on the gauge, then digest what you are seeing and react to it instantly.

If you want to tune a single and not melt things, be careful and go slowly. I really doubt a gauge is going to help much in the real world.

JB4 will auto switch to the boosting off the spring if it sees things way out of whack, Cobb does very well with adding in trim and avoiding lean conditions in the first place. If it happens, it’s almost certainly the end users fault.

" Good point on the JB4. I sure wish you made them for all platforms LOL. I'd buy 10 right now.
