this is the reason i still haven't bought a flash/tune

lol, learning everyday!!!

Of course, as I am getting some longer cranks these days it could also be the dreaded HPFP (or spark plugs? will get them replaced next week), but I hope that's not the case.

Anyway, if it's the flash (and I already got the half-engine light from it one some occasions) then I'm looking forward to the release of GIAC's stage 2+ flash now more than ever.

Happy holidays,

sorry to burst your bubble, but you should fix the problem first by changing out the spark plugs before you think the GIAC 2 flash will fix your problem because that flash is more aggressive than the stage 1...Did you scan the codes thrown when you limped, that would help alot to troubleshoot why you went into limp mode!

But when you run against DLSJ5's bolt-on M3, your cars are basically dead even.

I know bolt-on M3's are not pulling numbers that large on a dynojet.

I guess its the whole realworld hp vs dyno hp.

M3's are putting out close to the same HP #'s, just lower, much lower Tq..

when u guys say ("bolt on m3's) is that everything but the sc?

No bubble burst my friend, it's just that I had some minor previous problems with the Evotech (non-linear power delivery, half-engine light from time to time) but which may also be due to the ECU software I have, and which were the reasons why I already considered the GIAC quite a long time ago.

As I wrote, spark plugs will be changed early next week, so that won't bother me anymore anyway. I'll also get updated to the latest ISTA/P prior to getting the GIAC, which may already solve the problem.

Unfortunately, I don't have the means to scan for codes right now (haven't quite managed to go through with a BT purchase yet, I know I know I should do that), so it's unfortunately down to guessing right now. I still think that - if it's not the HPFP - it could very well be the flash that's caused the limp mode. Well, we'll see.

And yes I know the GIAC is more aggressive in that it runs more boost than I do now, which is why there will be some changes next week to accomodate (catless DPs, secondary HFC).

Hmmm. Do everyone a favor and find out how much boost the stage 2 map W/O meth is pushing; That way Jb3 and Procede V3 users can match that same boost level and see how much power they are making on 91 / 93 octane. That way you can compare different tunes @ the same boost level.

[enrita]

Highest sustained boost On 94 octane i have seen around 5500 rpm is 16,3-16,5 psi. Peak 16,7-16,9.

As long you don't have enrita's mods you should not test like this. We are picking up boost pressure in front of the throttle body, there is parasitic loss in the boost system which has to be kept as low as possible to avoid too much turbo stress. However, 16+ psi are impressive and don't seem to harm anything.

I agree that the EvoTech flash and it's evolutions are not as good as they sould be. Mine is throwing a tuner code and catalytic emission codes ( can be solved with O2 sims ). That's why I will test the Evolve ECU flash and probably the GIAC as well. Getting the GIAC in Switzerland seems to be a PITA.

Currently I like the concept of a Stage 1 tune with a JB+ flash version stacked on top of it. It works flawless on my e93 335i, all I need and will get from BMS is a signal line to switch the JB+ on / off from the cabin.

[J x K]

If enrita is running 16.7-16.9 peak boost & 16.3-16.5 sustained boost with no issues on 94 octane, then to my understanding a stage 3 procede user could reliably run 100% User Torque settings (about 15.7 psi) on 93 octane, correct? (Of course with the correct ignition timing backed by datalogs to avoid knock)


Apparently, 85% User torque will yield about 14.8 psi of boost and 90% user torque will yield about 15.1 psi of boost. Also, according to Shiv 's Custom Tuning thread, every 5% User Torque equals about a 1/4 psi of boost, which leads me to believe 100% User torque will yield about 15.7 Psi of boost.

Are there any safety issues running 15.7 psi of boost on 93 octane, besides your car's hardware & turbo longetivity?

IMHO, the procede running 15.7 psi of boost with the ability to correct ignition timing to the user's specific climatic onditions is safer than the GIAC flash running even higher boost levels... Of course I'm sure the GIAC tune would also have needed to pull a considerate amount of timing to run those boost levels safely..

Could anyone chime in? Shiv? JP?

I will make a separate thread so this one doesnt get intruded..

I ordered the BT tool and will probably receive it in the course of next week - then I can also check whether my Evotech flash throws codes or not. I'll also try to reproduce the situation where I went into limp mode, although that may prove a bit difficult considering I'll change some hardware next week.

Evolve is definitely an excellent company - keep us updated with your testing. I'll get the GIAC stage 2+ as soon as it becomes available and will do likewise.

[enrita]

With Giac i can run those boost levels because the flash has total control and perfectly calibrated values and timings.
Every run i do yield the exact same timings values and boost without oscillations.
At redline i see 13,8 timing advance which you cannot reach with a piggy even on meth.
If you run 100% UT the car will limp .

Got the BT tool and checked for codes - and I do have a HPFP problem (see below). Got to make an appointment with the dealer to check it out and probably have the HPFP replaced. The Evotech flash does throw the air mass manipulation code, BTW.

None in regards to meth failure.

The car will just attempt to compensate with fuel and timing pull.

So GIAC has a Stage 2 map for 93 octane? I could run that using Husky 94! I'm using that right now with COBB.

I can expect 416ish WHP without meth runing 94 octane fuel with FBO? If you use METH are you running the race map? Can you set up meth to come on at say 8PSI to ensure it never gets drained during daily driving?

The normal GIAC stage 2 map can be run with 93 octane, AFAIK. I'm running it constantly with 98 RON, which is around 95 octane. This will give you, according to a number of dynos I've seen (the conservative ones), around 360 whp. For more there's the race map for stage 2 with advanced ignition timing; you can only run that with meth or race fuel.

As for your questions regarding the onset of meth, that obviously depends on your meth controller. Almost all are boost activated, so yes you could probably program it that way. This has nothing to do with the GIAC flash, though.
