Re: The Fast and the Frugal 7.6

what kind of hardware problems are you having??

Slow boosting issue most likely due to a waste-gate not closing completely. Boosts to 20lbs but never really hits the requested 24. Car runs great just not as fast as it should be. About 1- 1.5 seconds slower fats time than it should be. That is why I would be rebuilding the turbos and possibly going to the SRMs & rods. Hate to pull the motor and not go bigger.

Re: The Fast and the Frugal 7.6

I have the run the ev14 550 with a 4bar fpr. I don't expect to keep this kind of mileage once the hardware issues are sorted and a final tune is dialed in. Two Years ago I would have gone with EPL but they only work with their own hardware and i like to fabricate my own. I have never been happy with the original stage 3 tune but I also keep changing hardware. It is fantastic having someone who is so knowledgeable with the platform tuning capabilities. Most likely i will be going with billet rs6 turbos and an hpx style maf so no real sense in trying to dial in this tune other than if Ryan feels something could be causing damage. our car is so smooth and powerful why would you want to change that?



I have never heard of recalibrating the DIS and because of where it gets its data I cant see how it would be needed. This is not an issue with the DIS under reading the fuel consumption, what I am getting is also measured on the OD and at the pump. This great mileage is purely due to not having hardware dialed in before the tune is tweaked. If a car is tuned when there is an issue with un-metered air entering the system and you later fix the issue then you will cause other issues with the tune. The series of events, hardware changes, tune tweaks has lead great mileage. Could have easily gone the other way and ran like crap with crappy mileage. These things are next to impossible to figure out when there are no codes. You can only log and have access to someone who can interpret the data.




I would say that 12L/100k is perfect. I spent most of the the early part of the year in the 15-17 range. Some of that was running maf-less. It seems out side of tune I gained mgs with ICM delete and coilpack conversion, gained more MPGs by replacing check valves and sealing minor leaks in vacuum and charge side , more when I put in the crankcase system.

Bob's DIS is recalibrated to account for his 52lb injectors

Ya n75 and all the usual suspects are new and double tested.

That makes sense now, thanks Ryan.

I wish I had a picture of the passat cluster when we drove it to Wuste...... 3.2L/100km @150km/h cruise...... now the lowest i've seen on the benzo is 8.4L/100km
