Hi everyone,
Does anyone know if UpRev ROM tuning software can support and handle higher end horse power cars? I was just curious is ROM tuning is capable of doing such thing. I've been looking around and "researching" from higher end cars what kind of ECU/stand alone/ etc their all using. It all ranges from anything from Haltec, Motec, AMS, and other companies. I've been looking into Pro EFI and talk to few licensed people about it. They said it's possible but to custom make the harness is minimum of $1500. Would anyone well over 800whp know anything about this, or could add their two cents in? Thanks! |

haha would anyone well over 800hp add there two cents, well since the only one that is is at gtm being worked on that's gonna be hard to find. It is running uprev though along with new mafs.
Edit: motec has been done but the harness is like $7500, fcon vpro has also been done but it's discontinued now, haltec has been stuck in pipe dream mode for the last 5 years, and you would need 4 dbw throttle controllers in whatever you do because the vvel takes 2 and the throttles take another 2.

And I don't know, I will admit... But isn't UpRev working well enough? EcuTek has great potential I guess, but is limited too...

Does the person with the Motec and Motec harness on the forums by any chance? I looked into the HKS Fcon, and I think it's great but the problem is their is only one licensed tuner here in Dallas. I personally think Jotech sucks a lot of balls when it comes to tuning.
I've been keeping in contact with Eric over at Haltech. It doesn't look promising at all, since he said no one in this community would ever buy it. Any direction would be great. A dyno sheet would be great too! Thanks! |

Are you on the DFW 370Z FB page? I used to live in Dallas, and the biggest issue with JoTech was that if you didn't own a GTR they didn't care much... And he's still gonna charge GTR tax rates... But Kenny does miracles with GTRs! The general consensus is go to AWD Tuning, or drive to Austin and go to UpRev

I don't think Kenny does miracles. I think Tony at T1 does miracles with GTRs. Anyway, no I'm not on the Facebook page. I'm just going to keep my car questions, events, and such with the forums. Thank you though! I guess I'll try out the Pro EFI and let everyone know how it goes, unless someone can assist me with some great information! Thanks again! |

And my bad, I'll keep the thread related to your original post. May I ask why you want to change to a standalone? Is UpRev lacking something? Or are you planning the most bitchin engine swap/setup?

fcon harness was done by gtm, motec harness was done by motec for gtm, really there is all of one shop that does public work that has installed a standalone in this car and you may have to wait a long long time to get it. If you call up motec they could probably make you one but the price will be rediculous. unless you are going to make 1000+ horsepower you can do it on the factory ecu with a reflash and higher calibrated mafs + lots of tuning.
Edit: try contacting the grand am teams to see what they use, oh wait hr heads so you won't be able to use that either hmmm you're SOL my friend, does PRO EFI know what VVEL is? once they do, odds they are going to tell you to screw off are almost 100%

The FCON cannot run a VVEL engine, so GTM might have attempted it to find out that hard way that its not going to work out. I dont know about a Motec. Id like to see any sources at all that say that either of those EMS projects ever ran.

The FCON V Pro, I mean, I guess you COULD run it... but while a full standalone, the FCON could not run even a VQ35DE without the stock ECU, let alone a VQ37VHR. So say you spliced it in with the VHR harness anyway (pretty easy), here are some problems:
1: you are stuck using MAFs. Speed density isnt an option with VVEL... then again, this should be the case with any EMS not just the V Pro, wouldnt it? 2: Accel / Decel fuel trims. So, you splice into your TPS sensors so you can manage your accel and decel trims. Thats going to be an issue when your VVEL system is adjusting engine load with the valvetrain rather than the throttle bodies. VVEL causes changes in engine load that are not directly reflected in the actions of the throttle plates. The VVEL system is the last thing to touch the air before it enters the cylinders and the throttles obviously are none the wiser... to get this to run clean, you are going to need an EMS that is aware of the VVEL system and what its doing as its doing it... and you are going to need a secondary accel fuel trim map that is based on the actions of the VVEL system. ami right? I see this as being more hassle than its worth as far as setup and configuration with any EMS at all unless one of the manufacturers steps up to the plate and puts the features clear and easy in their software. So, you can put the FCON in there and start it up... but I dont know who is going to enjoy driving that car for more than a few minutes without functional accel/decel trims

Most people are completely unaware of the VVEL system in the VQ37VHR, or what complexities it brings to the table. |
