AFRs at 10:1 on Dynoflash. What can I do.
Something else that has not been mentioned. The coolant temps when you were doing the datalogging and the AFR's at those points. The car has a very narrow window of "perfect AFR's". If you have ever watched Al tune, as I did all of last week and many times before, you will see him watch the coolant temps very closely. The car only runs "optimal" AFR's in a window between ___and___. No need to help other tuners with this information. Point is, if your car was hotter than when it was tuned OR much cooler (engine coolant temps) than the AFR's that you were measuring were not like they were when Al originally tuned it. It is NOTHING to see the AFR's move a full AFR point richer when the car is out of this "ideal window". Problem is if you don't tune the car IN this window then there is chance of the car going to lean and hurting the engine.
Look around at the results for the Buschur Racing "chip" for the flash, you can confirm the excellent results from stabilizing the coolant temps.

Let’s stop calling it a custom turbo setup and refer to it as a GT30R like hundreds of other being successfully tuned. Whether it be an old or an newer RNR kit, all the turbos are made by Garret as well as every other GT30R.
I asked if you could do it, you said yes. We attempted. The good news is the car still runs, the bad news is I am still unhappy. I am a very picky person and I apologize for that. However, I am a customer of yours.
Besides running a bit rich, I have no other problems with my vehicle. There’s nothing more to troubleshoot. The offending modifications have been removed. All that is left is a GT30R and an equal length manifold.
BTW, we must have had a few packets lost in the communication about reduced rate, I don't recall seeing that. Anyhow, I am sorry that we did a poor job of communicating and I appreciate your last minute efforts.
Thanks for your time.

This process now takes me one full hour of work to hook up and remove all the equipment ALONE - the tuning time is additional
You are a good guy and I feel for your situation, however the original problems relate back to poor parts design, and or instalation and while regratable dont result from my product.
The RNR turbo kit has come a LONG way and the current units work very well indeed, your set up never seemed to function well and the MAF sesnor, turbo and intake pipe combo did not work very well for driveability if I can recall. Also oil leaks and other problems were present which I can no longer recall as it has been well over a year since I first tuned it.
IF I RECALL our PM conversations of the past few weeks, I offered you a greatly reduced rate for a updated custom tune to re-tune the car for your new intake. However, you stated that you did not want to spend ANY additional money on this car.
Sorry that you are having problems with your car, however, you must realize that I incur significant expense in the form of air fare, hotels and rental cars to travel out to chicago and I have to charge for my time.
The best I can offer you at this time is to adjust your current tuning map for you - FREE of charge - if you ship it to me with some data of where it is rich and how much. This way I can get you closer on the a/f. Just send it into the address on my web site along with the information about what your wideband reads at various rpm points.

Notice to all non-vendor people trying to drum up sales by smack talking vendors and saying how much better you are:
Even if you pony up the $$$ to become a vendor you will not be allowed to smack talk other vendors, or the moderators..... so why do you think you can get away with it now while you are trying to cheat the owner out of advertising revenue by advertising on the site without becomeing a vendor?
Think about that, and get back to me when you come up with an answer that doesn't make you look like even more of an @ss.

About the coolant temp....
The coolant temp won't be out of it's "optimal range" after a few datalogged hwy pulls in 80 degree weather will it? Im just asking as a customer from south GA who could never get to you for tuning anyway, just trying to get a good AFR with my personal wideband.
Pm me if you would rather Dave, i appreciate your expert advise.

Depends gsujeff55, it very well could be depending on the air temps outside, boost levels etc. The window is fairly small. That's why Al will make a few dyno runs and then have to stop for awhile to let the car cool off. That is why Bill's road race EVO was flogged to death on the dyno while it WAS hot to make sure at Mid Ohio it would perform at its best.

XEDE.
I've gotten my curve close to perfected, but i just don't want that to be the 'hot' AFR then run lean as crap when the temp is optimal.
I guess all i really have to do is monitor it on a run just after it gets to running temp in some descent weather(hard to come by down here).
Thanks for your time, and you can call me Jeff...LOL

Not sure how the Xede works. It may not even have a coolant temp comp table in it, probably does as it is a piggy back. You may have a way to change it though.

Also - I am very close to unlocking the code in the ecu to control this feature and modify it to a more stable and controlable rate of change
