  1. It's possible the relay is bad, or failing. If it's still running after the engine has stopped, try pulling the small, trigger connector from the relay to see if it stops. If not, it's most likely a relay issue. If it does, it could be an issue with your ECT sensor/connector that didn't become an issue until you messed with it. (I know, "It's not broke until I fix it", right? )
  2. It'll run slightly rich. Best just to wait to do it all at the same time.
  3. 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.
  4. Just looking for a good set or R sedan rear springs. Thanks, Chuck
  5. 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?
  6. Have you checked the ECT sensor and its connector? The values from your logs look OK, but it's possible that there is a small delta that is messing with your fuel trim? Even a bit of corrosion on the connector can cause issues.
  7. I would suggest something that you can hear/see run. I pulled an engine from the PnP a while back. Never heard it run though. In the end, a waste of time and money. I've had good luck with finding something on ebay. A few places post videos of the engines running in the cars. The '01 RN motor we put into the wife's '97 GLT was from such a place. It needed cleaned up, but I didn't split the block/head. Just cleaned the oil pan, new timing belt, etc. Been doing great. Picked up another motor from the same place. Had a vid and it wasn't pulled from the car until after I'd bought it. (The other engine we bought had been out for a few months). The only other way i'd pull on myself is from a donor, on my property. I'd have to deal with getting rid of the rest of it, but pulling one in the yard sucks. I did it solo.
  8. Cool. I was just going to do blues, but had a bad one so I had to use some greens I had sitting around. No big mods yet, just wanted to get the M4.4 in the car (97 T5) and start messing with things a bit. Thanks.
  9. The acceleration enrichment tables as mentioned above. The 1's in the WOT table for all injector sizes?
  10. Anyone? I can't seem to find anything related to it in the big M4.4 thread.
  11. Does the injector basic adjustment factor take care of the scaling of the enrichment tables, or do you need to do that manually?
  12. Just to be clear, this needs to be done when changing from say oranges to blues? I've changed the adjustment factor and opening times based on the values in the Wiki, but haven't changed any enrichment tables.
  13. If you get around to it, can you post back up?
  14. Have you used this XDF and made any adjustments?
  15. Right, so what does this do for the P80's? Seems like a lot of extra "stuff" there.
  16. 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.
  17. 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?
  18. 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.
  19. Is there some documentation anywhere for the fan control parameters? Are the values in the XDF "stock"?
  20. 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.
  21. 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!
  22. 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?

  23. I started with an ECU connector and wires, so all I had to do was connect 3 wires to the OBD-side of the USB. The only time I had an failed flash was when one of the wires came loose. It would still flash if everything stayed in place. Once I grabbed the OBD connector from a car in the JY, I haven't had an issue with a bad connection. I've only flashed maybe 10 times, but it works. You say it's "like in picture", but your set-up isn't, seeing as you're connecting ground to #4 and not #5. Are you also positive that you are connected to the proper pins on the OBD for flashing?
  24. It is all just plugged in at once. Wired as the pic on the Wiki, including connecting OBD pin 4 to ground. I just made a special flashing harness from old ECU and OBD connectors. Plugs into the ECU and the OBD/USB cable.
  25. I use a 14V power supply to feed pins A12, A26, A27 and B8 as well as pin 16 on the OBD connector. Flashes just fine.
