That's still on the table...ive just been disappointed. FBO minus fmic on pump gas i only dynoed at 335 rwhp/355 lb-ft. Underwhelming. I'm having some issues with the car and they might be hardware-related. Taking to the dealer soon. After that's sorted I'll try the procede again, but if it's not performing well then I'll try the JB4 for a few weeks. Just seems like people are putting down really impressive numbers with auto tune maps and E85 on the JB4. Procede requires a lot of fussing it seems and I don't have the time/knowledge to be constantly messing with this thing.

vishnu procede was the bench mark for teh ISO jb4 gen 5. no surprises here. terry has better customer service. terry has recognized the value in a flash + piggy and works indirectly with cobb. congrats, OP. your power level increase is awesome.
shiv probably will never concede that a flash + piggy was the best option last year. not until the "procede flash" came out did people realize a piggy is limited to fueling ceilings. i, for one, will continue to use cobb and piggy combo's. terry is primed to take over the piggy market. the only thing vishnu has going for them lately is the single turbo and the flex fuel kit. the procede flash helps out when you're at the limit of a piggy. cobb + jb4 is essentially a better option. |

Eitherway, as long as your happy it doesn't really matter what tune you use. Enjoy Last edited by Jeff@TopGearSolutions; 11-14-2012 at 10:55 AM.. |

Ok, so I ran map 5 as that made the highest power numbers. I would however like to re dyno the car on map 7 now that I am on 100% e85 and I was not the day of the dyno.
I am very happy with the switch and to clarify I have been running the 50/50 mix on the jb4 for several months with no problems NONE. I only bought the bms flash for the reasons I previously stated 100% e85 usage and Timing advance. As terry told me this flash may not be for everyone as its not cheap but I think it was well worth the money!

On the tuning end if using more than 40-50% E85 they suggest their flash along with the JB4. You load the BMS flash at home in your driveway. You do not need to remove and ship around your DME. When going in for warranty work you can also unload it from your driveway. When new maps and tricks are made you again can load them in your driveway without shipping things around and having down time with the car. Simple. Plus, the device they use for the BMS flash maps, the Cobb AP, has a killer resale value if you ever sell the car. Mike |

yeah its no brainer at all and if you have an issue you can always test both alone and see if its tuning related

1. You do not need anything other than the JB4 G5 up to 50% mixes. The benefit past 50% is minimal performance wise (about 10hp more MAYBE) but it will allow you to use only one pump obviously. 2. The Cobb, if you decided to flash with BMS flash also, has significant resale value. Its not like you lose the money on the flash. Don't forget the Cobb is an entire tuning solution in itself which you can update with free downloads. The main benefit left for the Proceed is the ability to go from 100% ethanol to 0% without resetting anything. The reality though is that this is one press of a button over the steering wheel controls. It really isn't a big deal and if you forget to do it, no your motor isn't going to explode. You will CEL and misfire though. I see benefit to both and obviously the sensor serves a purpose and is closer to the correct/ideal solution. That being said, JB4 is putting down big numbers and has the added benefit of a Cobb and for 100% E85 use. |

This is with E50 , see after 6k just leans out, lpfp pressure drops like 20 psi and trims shoot up to max, around 450 whp i think:

Exactly, you would need to log first. I was maxing fuel trims at 30% E85 with the JB4. |

You may have a car that only runs 30% ethanol, but if that's the case then there really isn't much difference between proceed and jb4. Either one will then require you to buy something else like Cobb or flexfuel kit. I suspect you can run up to 50% though since most people can. You only need about 40% mix fyi to get full timing at ~18psi safety limit. Whichever you choose though, I advise you start with just the tune. Then you can opt for Cobb or flexfuel if needed. Don't expect the gains to be anything near the 0-50% level when you go from 50-100% though. The bulk of the performance benefit is realize on tune only. |
