malibud Posted August 12, 2014 Share Posted August 12, 2014 Ok I have the Jim wolf 300z ecu with an 1982? turbo set up in a 240z. Idle timing is set at 8 degrees . I believe I have the crank angle sensor from a vg30e like they want. I have flipped it both ways no change. I checked the placement of the distributor. At 0 degrees, and the #1 piston set TDC the rotor points to #1. the screw holes gives me very limited adjustment is there any way to change that? I thought I read in search that Tony D said there was a way around that but did not explain. can I take the distributor out and move it over one tooth ? I going to junk yard today to get another CAS wheel . thanks Dan Quote Link to comment Share on other sites More sharing options...
mattb3562 Posted August 13, 2014 Share Posted August 13, 2014 Not sure about the jwt setup, but on megasquirt, my l28et idled best around 18°. It was pretty rough at 10 when I was getting it running. Quote Link to comment Share on other sites More sharing options...
malibud Posted August 13, 2014 Author Share Posted August 13, 2014 thats my problem its not running right because I cant advance my timing. trying figure if I should move the dist. one tooth . Quote Link to comment Share on other sites More sharing options...
mattb3562 Posted August 13, 2014 Share Posted August 13, 2014 If u end up needing the CAS from an 82, message me. I have a brand new one if I can find it. Lol Quote Link to comment Share on other sites More sharing options...
malibud Posted August 13, 2014 Author Share Posted August 13, 2014 Thanks but I am using one from a vg30e maxima distributor . I got a spare just in case. I think I figured out my problem one second look. When the #1 piston is at TDC and the rotor is pointing to #1 the timing mark is pointing to 10degrees . I think my dist. is off . I am a little worried about moving it and being totally out of wack so I might take it in to the shop. But if I mark the dist and move it wont it slide back into the same slot ? because of the oil pump thanks Quote Link to comment Share on other sites More sharing options...
Tony D Posted August 14, 2014 Share Posted August 14, 2014 CAS drive... If it's off, it was installed wrong or the drive gear slipped on the shaft. Only way to fix is a new shaft or praying you can get it right rotating teeth on the drive end. Quote Link to comment Share on other sites More sharing options...
malibud Posted August 15, 2014 Author Share Posted August 15, 2014 I can put it in correct time but cant get the the dist. hold down bolts in the hole. Thought about cutting the end of the slot off and use a bolt with a washer to hold it down. Idled great at 20 degrees. From reading your earlier post it seems that I have to drop or loosen the oil pump to move the dist over a tooth. I tried moving the dist over but the oil pump would not turn . Can I remove 2 screws from oil pump and loosen 2 and move the oil pump shaft over ? "Only way to fix is a new shaft or praying you can get it right rotating teeth on the drive end." are you saying I need a new dist shaft ? THANKS you are very big help !!

Xnke Posted August 15, 2014 Share Posted August 15, 2014 You can try dropping the pump and indexing the shaft as shown in the service manuals and the how-to books, but if that can't get the job done then you may have slipped the press-fit gear on the spindle, and it will either need to be re-indexed and pinned, or replaced. I'm betting the oil pump drive spindle has been incorrectly indexed when the pump was replaced at some point. Quote Link to comment Share on other sites More sharing options...
NewZed Posted August 15, 2014 Share Posted August 15, 2014 I believe I have the crank angle sensor from a vg30e like they want. I have flipped it both ways no change. He's not using a stock L28ET CAS he's modified with a later disc, I'm guessing, from what he wrote above. You mean the disc with the holes in it, right? There are a variety out there with holes in different positions,from what I've been able to figure out. But if the one you have is that close, 12 degrees, you probably won't find better since you're off the stock application grid. You'll probably have to mess around with the drive gear as suggested or just modify the hold-down clamp like you described. I'm assuming you did something like cgsheen describes in Post #20, here - http://forums.hybridz.org/topic/111877-north-idaho-eastern-washington-280z-l28et-wiring-gurus-or-anyone-willing-to-help-a-knucklehead-out/?do=findComment&comment=1052558 Quote Link to comment Share on other sites More sharing options...
malibud Posted August 15, 2014 Author Share Posted August 15, 2014 New zed that is correct I am running a remapped ecu from a 87 300zx I need the CAS wheel for it to run right. I can't see too much harm in cutting the distrubutor so that I can get more advance seems like it would be the easiest route. But I will look at oil pump drive spindle indexing too. Thanks for the replies .. Quote Link to comment Share on other sites More sharing options...
Tony D Posted August 17, 2014 Share Posted August 17, 2014 Easiest... So then where's your reference point for correct? Drop the oil pump, re index the shaft, and reinstall. It takes all of twenty minutes and is FAR easier than hacking up a distributor IMO... Quote Link to comment Share on other sites More sharing options...
malibud Posted August 18, 2014 Author Share Posted August 18, 2014 Thanks Tony well do. I always find your post very informative and at times very amusing Quote Link to comment Share on other sites More sharing options...
