Aren't you running a stand-alone ECU?

Ms45 is no good for programming, i have been through 3 piggy backs, 5 tuners, and had to give in to the MS43 swap, which is proving to be a PIA because the harness connectors are not the same (more than just the o2 sensors as once believed). My car has been down for 2 years with a built engine but no effective engine management.

First concern was trying to find a great tuner that could work not only with the standalone I would choose, but also be familiar with BWM. I have a huge concern that I will purchase a standalone and no one will know how to tune it from scratch. The second concern was the price, 4k for a system that may or may not work in a huge concern of mine. I was assured that each piggy back I purchased would work (non-did), so I don't want the same outcome at 4x the cost. If I could find a tuner in Houston that was capable and reputable, I would commit to it hands down. Third concern was functionality, I want to maintain ALL the factory comforts....

I would love to go ProEFI to run e85, but even when I called them I was told they did not have a system for my vehicle. So it would take a lot of time to get the genetic system calibrated.

MPower here in Houston have spent a lot of time on the car trying various solutions. I'm considering having them put the car back together and finding an expert at one of these standalones.

The MoTeC M130 will work, but it's a bit of an investment. Nothing beats it's flexibility, however. The MS43 swap should work well for the lowest cost out of pocket. That will need a full engine harness and O2 sensors.

i love Vipec and its capabilities.
i was really lazy to hassle with dual vanos and stock stuff as i run car more for race and fun purpose but anyways Vipec i88 is the ECU that i would recommend to go for. we ran them on many different applications like a 2013 Nissan Patrol, E46 M3, Evo, STI etc.

This MS43 harness differs by more than o2 sensors, the alternator plug and knock sensors are also different. Mechanic doesn't want to cut the wires so it's taking quite a bit of time. They have have spent so much time on my car that they now work on it in their down time.

The problem is I don't have the tuning expertise like u guys. Maybe it's time to educate myself on tuning...smh

Now I have several files from ess and from active auto, if I load them to the MS43 ECU, will the files be compatible? We had the MS43 ECU recalibrated with my vin...but will the files load? I still have my Map3 ECU that should work to manipulate the MS43...hopefully....

MS45 files or MS43 files? MS45 full read is 1024kb whereas MS43 is 512kb. So i definately wouldnīt try to flash a file from a MS45 to a MS43, i canīt even remember of any software accepting that approach.

Oh man, that reminds me of the Autologic days for Fords...'tuning' was there, but missing so much.

MS43 and MS45 aren't even the same CPU architecture. One is useless for the other.

What the hell is this ? Seems really cheap, can it do "Everything", or does it have major limitations. For example, could someone with MS43 buy an Ebay turbo (please no Ebay turbo jokes) and successfully get it "tuned" using just this software ?

Curious,

So all my current tune files from the MS45 are useless. I even have the prototype ESS TS3 tune that did not work for me. Guess I have to use the piggyback and start from scratch or request the TS3 file for the MS43 from ESS. Gonna have to see how the file does with the larger throttle body and more aggressive cam

It seems as if the people with TS3 on MS43 have been pleased, but I don't know how that tune will react to me drawing more air

I understand the concepts of AFR and optimal ranges, I even have a good idea about timing....but where do I begin to learn the tuning game? Getting the feeling I'm gonna have to learn for myself and learn quick!!!

Especially because I found a larger supercharger that bolts right up, produces a third more air. I feel like that with this larger throttle body should set some serious records and that's where I am now going if I can learn to tune....

Anybody putting on a workshop?!?

Just to clarify, the tunes are not bad, IRS that the ECU is too smart. The tunes will work for one pull, but then the ECU compensates and configures to adjust back to factory specs. Doesn't matter how much fuel or timing u pull, it will eventually compensate and take u back to square one.

Buy this book on Amazon for about $17 dollars, also I'm pretty sure the author Greg Banish does put on seminars.
