Artemis Posted March 13, 2009 Report Share Posted March 13, 2009 From Moetes.net "This is for GM memcal-to-chip adaptation where you have the little blue 'box' memcal that has the integrated knock sensing board. Those little puppies are a real pain to hack apart, and this adapter makes it MUCH easier. Typically used on ECMs like the 16183247 and that sort of thing (Grand Am, Grand Prix, etc). Chip (C2 27SF512) sold separately." If I understand this, it basically allows you to use PROM chips to mod your OBD 1.5. Anyone else looked into this? Could open a world of tuning for us 95 guys/gals. Quote Link to comment Share on other sites More sharing options...
GOT2B GM Posted March 13, 2009 Report Share Posted March 13, 2009 I'll have to show this to Jamie, basically breaks it down to OBD 1 tuneability Quote Link to comment Share on other sites More sharing options...
Crazy K Posted March 13, 2009 Report Share Posted March 13, 2009 ??? the OBD 1 and OBD 1.5 (as used in 3.4 dohc cars only) use the same type of prom chip setup. Both have a UV erasable chip with the .ecu/definition info to run the car with, and the ESC chip. the issue with 1.5 isn't the ability to use an adapter, it is the ability to tune. there has been a moates adapter for years that could do this job I think... and BEN sells his chips with a Moates adapter I believe Quote Link to comment Share on other sites More sharing options...

19Cutlass94 Posted March 13, 2009 Report Share Posted March 13, 2009 94-95 has no removeable PROM like OBDI. It is a flash based computer. Quote Link to comment Share on other sites More sharing options...
Crazy K Posted March 13, 2009 Report Share Posted March 13, 2009 94-95 has no removeable PROM like OBDI. It is a flash based computer. yes, EXCEPT 94-95 LQ1 Both Psychomatt and Gnat-go-splat have modified chips in their 94 LQ1 CSs, the modification is for the DIS data stream only. IF YOU COULD DECODE AND MODIFY THE INFO, you could re-program. Quote Link to comment Share on other sites More sharing options...

jtwmechanic Posted April 15, 2009 Report Share Posted April 15, 2009 i wish i had the obvious schooling that you all have so that i could interact on this post, but i don't. i am however interested in being able to tune(reprogram) my 95 CS, please update.

jtwmechanic Posted April 15, 2009 Report Share Posted April 15, 2009 could someone here tune it for me if i sent them one of my spares. Quote Link to comment Share on other sites More sharing options...
CSI_MuNkY Posted April 15, 2009 Report Share Posted April 15, 2009 I got an e-mail back from Moates, they forwarded my e-mail to Tuner cat and they got back to me as well... BOTH told me that there is nothing they can do for the OBD 1.5 cars. Hi Jamie, Unfortunately, we don't currently have anything for these cars. They used a unique PCM that was somewhat similar to the LT1 PCM but quite different when it comes to the calibration and programming process. Best regards, TC C.A.T.S. http://www.tunercat.com Hi Jamie, I'm not aware of support existing for these applications, but I'm certain it could be done if the software side was available. My hardware should work for those vehicles to reflash. Adding TunerCat to the CC list on this response, as he may have some comments in this regard. If anyone is able to provide software support for those applications, he'd be the one. You haven't been the first person to request this sort of thing. Best regards, Craig I might be able to find someone in the f-body world that can shed some light on it. Fuck that, I'll swap to OBD 2...... some day Jamie Quote Link to comment Share on other sites More sharing options...
jtwmechanic Posted April 16, 2009 Report Share Posted April 16, 2009 so basically they are saying that they can create a factory prom but not after market tuned ones???? Quote Link to comment Share on other sites More sharing options...
CSI_MuNkY Posted April 16, 2009 Report Share Posted April 16, 2009 Moates says their hardware SHOULD work, but they have no programs to run off of. Even if we found a program that could do it, who is to say it would be fully tunable? IMHO, an OBD 2 swap is in order for me... I am sick of dealing with 1.5 BS If I go out to the car today and get it running, it will get an OBD swap of some sort, if it doesn't run I will be looking for a OBD 1 or 2 car to replace it with.

I'd rather have something I can plug my laptop into and tune on the fly Jamie OSTRICH 2.0.... i'd have bought one already but don't see the need unless the tune is that bad or something entirely new I eventually plan to turbo the car, but that is at least 2 years away. So adjusting the tune while I'm at the track or whatever would be beneficial. Jamie Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 17, 2009 Report Share Posted April 17, 2009 i just bring my chip burner with me everywhere... and also leave three of the prom cover screws fairly loose.. hell, it only takes 30 seconds or less to burn to the chip, then i swap them, and the whole process is 60 seconds or less. and thats OBD1... but if you have the money for the ostrich, as soon as you hit the enter button after changing any value, it updates, so technicly it takes .100 seconds to change the tune...

jtwmechanic Posted April 17, 2009 Report Share Posted April 17, 2009 i am really glad to have run into you guy's here. nobody around my area is into these like you are. i am running a 95 CS 3400 w/3500 top end swap, do you think a good tune will improve my power( i could care less about fuel milage) unless it is a considerable difference not much use in even messing with it Quote Link to comment Share on other sites More sharing options...

YEAH!!!! Are you still running the stock computer/wiring harness? I ran a 3400 with a 3500 manifold for a while on the 3100 computer before I switched to 1997 PCM/harness with OBD2 and tuned it. There must have been a 20% or greater power improvement, along with better driveability and fuel mileage. My setup, complete, gets the same (or sometimes better) fuel economy when compared to the original motor. Quote Link to comment Share on other sites More sharing options...
