RobertISaar Posted May 24, 2007 Report Share Posted May 24, 2007 has the 3100 and using a 282 problem been fixed or not? i really dont want to have to use MPFI if i already have SFI. (question was inspired by some 3 and 4 year old threads) seems like it would be possible, but i dont work for GM. Quote Link to comment Share on other sites More sharing options...
slick Posted May 24, 2007 Report Share Posted May 24, 2007 Yes, you can do it. It's been done many times over, especially in the J and L body world, and is very very possible in the W body's. It's just that w-body guys are a bit slow to modding there cars. BTW, even though you have a 3100 and it says SFI, it's only SFI for a minimal amount of time. 95% of your driving is already in MPFI.

RobertISaar Posted May 24, 2007 Author Report Share Posted May 24, 2007 correct me if i'm wrong but you're talking its only SFI while idling, right? because of how fast the injectors have to open, close, and get ready to do it again, its basiclly batch fire because of how fast they cycle? oh and it should work using an obd1 compter then, right? i'm buying an entire kit to convert from 1.5 to 1 from someone on the 60* forum and the 282 from our very own xtremelumina92 (i guess its SMOOTH now, as i'm reading through my messages) Quote Link to comment Share on other sites More sharing options...
slick Posted May 24, 2007 Report Share Posted May 24, 2007 You can use a 282 with OBD II. Again, it's been done numerous times. In fact, if you swap to OBD II, you have TONS more tuning capabilities over OBD I. OBD I is limited as to what you can really do. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted May 24, 2007 Report Share Posted May 24, 2007 I think the biggest part about this 282/3100 ( atleast I know for me ) is with the OBD 1.5, keeping the SES light from coming on. Quote Link to comment Share on other sites More sharing options...
slick Posted May 24, 2007 Report Share Posted May 24, 2007 IIRC, there is a fix for it. I know the L body guys still on 1.5 with a 282 don't complain about the light. Quote Link to comment Share on other sites More sharing options...

RobertISaar Posted May 25, 2007 Author Report Share Posted May 25, 2007 suppose i go the OBD1 path, would i lose anything? i didn't think you could get a 3100 to work with a 282 while using 1.5... was told that the motor would stall at random. if it'll work though i'll keep 1.5 for a while and when i have the money i'll go for obd2 Quote Link to comment Share on other sites More sharing options...
slick Posted May 25, 2007 Report Share Posted May 25, 2007 A bit more tunability. That alone makes a difference with gas mileage, power/performance, and in general the way the engine will run. I know a few guys that are running 3100/3400 282 obd 1.5 L body's with no problems. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 25, 2007 Author Report Share Posted May 25, 2007 what did they do to keep it working? and i can't remember what an L is? Quote Link to comment Share on other sites More sharing options...
slick Posted May 25, 2007 Report Share Posted May 25, 2007 L body is a Beretta or Corsica. As for getting it working, to be totally truthful, I'm not sure. I would search over on http://www.bstuff.com or on http://www.60degreev6.com for definate answers. I even think the j-body website may have some info on this as well. Like mentioned above, the w-body guys are a bit slow to doing modifications other than an intake, udp, and exhaust. You'll find more info on available mods on those pages.

19Cutlass94 Posted May 25, 2007 Report Share Posted May 25, 2007 FYI, theres a vaccum port in the plenum that helps with the shifts/with the tranny, thats one that needs to be blocked off. There is no issue with random stalling etc etc etc. The tranny is controlled by the ECM, with the help if the electronics/vaccum. This is something I want to do next yr. But only thing holding me back is the wiring issue of keeping OBD1.5 and to keep the SES light off, and all that bullshit Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 25, 2007 Author Report Share Posted May 25, 2007 are you refering to the vaccum port thats mentioned on the emissions sticker under the hood that says: to 4 speed tranny, otherwise capped"? Quote Link to comment Share on other sites More sharing options...

You hit that on the head. This forum has a million wannabes, few if any follow through. Either not enough money which I can understand with most of the guys going to school. and I also understan that putting money in one of these old cars is a bottomless pit. My pit is about 34k deep. I have hundreds of emails asking how to to this or how to do that yet I see few going through with anything. one of the problems with this site is that nobody searches. There is alota info on here but you get tired of repeating your self time after time. Jud Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 25, 2007 Author Report Share Posted May 25, 2007 i'm still buying that obd1 conversion kit but i might use it or just sell it. say if i did use it, if i found the right file on the internet it should work correctly? i should be able to use the prom for a 3.1/282 combo and all will be well? another thing: what would be all of my possibilities of changing the final gear to?
