  1. Look in the Diagnostics Disables. Change both banks.
  2. The wife's ECU is the std VS -607 bin that was modded for the '97 GLT(-936) AirCon controls by Piet. No mods incorporated. Just the adjustments to the fuel/ignition/turbo maps for the LPT starting point. (Copy/paste stuff from the -936 bin) My '97 T5 has the std VS -607 bin currently, with only minor boost tweaks. No other mods. Both have the changes made for running different injectors (Blues in hers, greens in mine) and the standard diagnostic disables. Been too busy with house and new baby stuff to do much more messing about at the moment.
  3. Just a quick question. Both my wife's '97 GLT and my '97 T5 are running flashed ECUs. For the most part everything is groovy, but sometimes when you go to start either car, the engine will stumble right after start and the CEL will flash. It will then clear up and act normal. 80% of the time it will fire up just fine. No DTCs are being stored, and the cars run great. Is this common, or do we have something else happening?
  4. Right, so what does this do for the P80's? Seems like a lot of extra "stuff" there.
  5. Yeah, I think there is a missing piece of the puzzle. There is no way (That I see) in the MY98 cooling fan control to change the fan speeds. A quick search online shows that there was a (PMW?) control module added to the system in '01MY, but I haven't found any reference to that being a "mod" here.
  6. Yeah, I figured out what each was for, but was confused about the difference in numbers of speeds vs thresholds/runtimes. I was also confused about the 5 different speeds part. I didn't think there was any modulation in the fan speed, just the high speed for the cooling fan (and low for the AC). Is there a fan controller on a later model that this is making use of?
  7. I guess I'm missing some part of the picture, as this is what I have. I don't see what to do with it to make changes.
  8. Is there some documentation anywhere for the fan control parameters? Are the values in the XDF "stock"?
  9. OK, well the changing the values mentioned above disabled the pre-start listener and I do have proper OBDII function. Haven't tried logging yet, but we really haven't made too many changes so far. (Just injectors and minor boost threshold increase). One thing I'd like to change is the idle bump when the AC is turned on. It tends to drop a bit more than I'd like at idle with the trans in gear. Is this the chart to change that? The top is the std -607 map and the bottom is the stock -936 version. Or any suggestions to bump the idle up a touch when the AC is engaged? It was doing the same thing with the stock ECU. [/img] I'm also still not keen on the cooling fan not engaging whenever the AC is turned on, like it did with the stock -936 ECU, but apparently that is what these things do. Since there is this rad fan control XDF available, maybe I can tweak those settings a bit. Just need to dig up the details behind it.
  10. Is it possible to get a clarification on this for the auto bin? (Sorry to dredge up the old post) Should the addresses and changes be 3D69 and 3D6A (12 88 to 00 00) and 4113 and 4114 (7D AD to 7D AE)? Thanks!
  11. OK, so I'm finally getting around to putting together a "base" tune on the hybrid -607/-936 bin for the wife's '97GLT. I'm taking the -607 that Piet put the -936 AC routines into as the start, and transferring some base values from the -936 bin to get us something to begin with. @Turboforslund put together the XDF from the -936 chip that I sent him, which was awesome. Looking over things, the first thing that stands out are a couple extra RPM axes in the -936. [/img] [/img] As you can see, the RPM value ranges are different, and he notes their possible usage in the first pic. Comparing a couple of the charts for the affected maps [/img] Should I worry about trying to add/change those axes in the bin I'm putting together, or just leave them as the fixed major RPMs? The "start" point for the tune is an '01 LPT motor, Japanifold w/ 16T and exhaust, and blue injectors. (No COP or ExVVT yet) Maybe leave the fixed Major RPMs and alter some of the values in the other RPM ranges on the -607 to match the -936 stuff? Thoughts? Links to the -936 bin and the XDF XDF 936 BIN
