  1. Yeah, I had to do those on both of our cars this season. Kind of a chore, but so nice when they're fresh.
  2. I'd be curious for that as well. Looking for some more references for the LPT motors.
  3. What is the code on that ECU? Those '97 AWD LPT cars are similar the US '97 GLT LPT, and probably share the same issues. They are M4.4 engine management, but are still using the old 850 ECC modules, I was able to get someone to pull the .bin from the '97 GLT ECU we had (-936) but I never had any luck either reflashing that ECU, or using that .bin on a 98MY M4.4 ECU. The car would never run. It took a 98MY M4.4 ECU and a special .bin to get the car to run properly AND have working AC. The car would run fine on a 98MY ECU, but wouldn't have working AC with or without the "AC Mod". Find yourself a 98MY M4.4 turbo ECU to use for flashing.
  4. Unlikely, seeing as NONE of the 850Rs came with an M4.4 ECU from the factory. It's possible it's already been upgraded to M4.4.
  5. Currently just a set of used "R" coils. I need to do this to the wife's car, but we're also going to activate the exVVT, so just an extra bit of wiring needed. Have the .bin ready for it. Now I'm trying to find some good info on boost control settings, just to turn things up a little bit.
  6. Just finished up the VAST DIY COP conversion while doing the manual swap on my '97 T5. Works Great! I integrated the new COP wiring into the engine harness by making jumpers between the ECU connector and the 24/15 connector out to the engine harness. All tucked away out of sight. IMAGE
  7. Yeah, I was a little confused, as they're a "time", but the question on the values was still relevant. They've been running at that max correction value for the past year, but my injector constant has been wrong, so hopefully that clears a few things up. Thanks again!
  8. So, do I just use the 4.9725V value for those values over 5V? Flashing the ECU in prep for a restart this weekend, and would like to have that sorted. The previous tune had defaulted to the 4.9725V value, unbeknownst to me anyway, but if there is an alternative, I'd like to try it.
  9. OK, well I'm going on the info from @Piet's post I'll have to check which greens I have (From an '04 P2R engine), but if the max value is 4.9725V, how are the values of 5V+ usable? Thanks for the Injector Calc link!
  10. Is there a "Maximum" value for the "injector opening time by voltage"? I'm configuring the new .bin for the manual swap/COP upgrade on my '97T5 and having an issue with the values for the "Greens". For the 5.00V and 5.99V values, it calls for 5.8177 and 5.1556. When I commit the values, they both revert to 4.973. The rest of the values look to be "correct". Also, the "Basic Adjustment Factor" for the greens should be 0.7188 (according to Piet's post from a WHILE back) and not the 0.8125 shown on the Wiki page, correct? That would explain a few things the way the car was running before I pulled things apart for the manual swap.
  11. @Piet Could you send that my way also? (I can't access the attachment)
  12. Yeah, the 97MY LPT 850's had a different AC routine. We ran into the same issue with my wife's '97 GLT. Piet sent me a .bin that was the -607 bin with the AC routines modified to those found in the -936 ECU (The 97 GLT 2.4 LPT ECU). Shoot me an email ( and I can send that to you. I haven't had time or inclination to compare what was different between the std -607 and the -607/-936 .bins, but you can probably figure that out and apply the changes to the -608 .bin
  13. Yes* * The '97 LPT 850s are "M4.4" cars with the older EEC modules. A 98MY M4.4 ECU modded like above, or not, will not work. It took special coding to get things to function. Now for a HPT M4.3 car, yes, changing those bytes works. I also have a '97 T5 HPT car with an M4.4 conversion, and the "AC Mod" works just fine.
