Ive been burning chips for a few months now, and have had some progress. Its still not right though. I came across a piggyback dfi system very cheap, and am considering it. I like that it uses map (unlike my MAF), and that I can make changes whenever I want. I have part #, but cant find any reference. # is 74305-c , can anyone tell me what this is for? Im told its off a 88-89 camaro. Ive read the manual on site, and it seems to be easier than burning as well. It may not have as many functions as burning, but i think this system would be better for me. My mods are in sig, and I would appreciate any pros or cons to this setup, as well as what part #this is for.
Thanks in advance,
Joe

Accel sells one but it's for use with their ecm, Crane used to sell one but that was for CCC applications

 

I know this is an Accel DFI, model # is above. It uses ecm that plugs in, using harness that goes between factory harness, and factory ecm. The guy has all of this, software, cable to laptop, and manual as well. All for $300/neg I dont know everything about this setup, but I believe this price is pretty good. Any info would really be great. Thanks,
Joe

 

I think your best bet would be to contact Accel direct, or possibly Rich at cruizinperformance.com or another authorized installer.
