PACECARTA, Looks like there are software issues that need to be sorted out. My CComWP software indicates version 2.051. However when I attempt to execute your pdf instructions, I get: Step 1) under 'spark functions' I do not have 'Spark Offset vs FEC. Only Spark Offset ATS and CTS. Step 2) No...

PACECARTA, Thanks again. Before taking these steps, it also seems logical to reflash my unit to 2.010 (following the instructions in section 26 of the manual). However, when following these steps the flash ecu option in greyed out. Would you think the a call to Comp would be helpful for getting...

PACECARTA, Humm!! Since the xfi is from 2005 (??) it must be 2.01. I will check tomorrow. I found a file named ccwpxfi20109B in my downloads. My guess is that my xfi was flashed with 2.05 when Comp checked my unit out?? When I connect to my xfi tomorrow, if I find it is 2.05, would you...

PACECARTA, Thanks. 2.01 versus 2.05?? How do I check this out?? Does this mean Comp's operating system or something else? It is possible that Comp installed 2.05 when they checked out my unit. Is there a way to get back to 2.01?? More to learn.. DGC

Thanks Again. Carefully scaned my XFI manual and will need more details. My manual has 6.2.2 Ignition Type, not Spark Cut Rev. Limit. When I go to Operational Parameters, I am not finding anything with the value of 50. Is it possible my Manual (dated 2012) is not correct? On your second point...

FYI, It ran fine with this tune.

Forgot my tune.

Thanks Chuck, Please check attached log. I used a nearly complete dash. If i left something out, please let me know. Or if I screwed up the log, let me know as well. I should add that with ignition, the engine fires, then dies. With stock ecm, it will fire and run. Please let me know what...

Back again with yet another 'will not run' issue. 87 turbo that has been in continuous mods since purchased over 2 decades ago. Current condition has engine running with stock ecm, but not with xfi. Most recent mod was a complete capar's wiring harness. Nostart tree checks find 1) fuel fine, 2)...

Looking for anyone that has installed a Caspers wiring harness. Their instructions require loosening/removal of the passenger front inner fender, which I have done. The two bolts on the bottom of the passenger floor, that secure the pair of cables that go the the ecu, have been loosened. I...

N2Buick, Still struiggling with a nostart condition. Your prior e-mail indicated that you have a XFI 2.0 box. Since I am not yet sure where the problem lies, checking another xfi box would be good. Would you be willing to sell your box? Thanks, DGC

thanks. '87. will try to find prior posts.

working through shop manual checklist for nostart condition. i noticed the wire colors in the ecu harness (a,b,c,d) do not all correspond to those specified in the shop manual. some do but some don't. anyone find the same with their car? as noted in the title, this buick is built in canada...

thanks to all for educating me on the 200-4r. set tv cable as described and am back to more abrupt shifts. the car was driven ~6 blocks around the neighborhood, with soft shifts, i am curious to know how easy it is to burn the clutches with very light driving with the tv cable having only a few...
