I was a little curious why none of the built N/A guys don't use this. it looks like the tables will not only cover high rpm already but has alot of low rpm inj. control that is needed for large injectors and a stable controlable idle and a few other interesting things I never really thought of befor but may prove worth while.



anyway does anyone know where the hack for this can be found?

 

If it's for the '165 you've got my attention. I need something with extended tables since the engine I'm building will make power at 6500+.

Edit- nm, it's for the '749. I've looked into doing a '749 swap so I'm still interested.

 

well it's really 707 and 708 but I have heard of it being used in the 749 with great results. the 707 is a much easier pcm to come by vs the 749. I would like to hear about your swap if you do this. some of the things in that code really have me wondering what they do. I plan to start playing with this code real soon here and the more people on board can help a code grow in support as we have seen other do in the past.

 

It lools like the 707 and 708 were used on PFI 4 cyl engines so I would guess that there is only one inj. driver in the ECM. The 749 ECM has two inj. drivers in the ECM so it has an advantage, but the 749 code doesn't take advantage of this. The 730 ECM is pretty much a 749 ECM with one injector driver.

The $8D code is hard to beat in terms of idle stability and every other aspect of drivability when compared to other code of the era. It is fully documented / hacked. Tha saujp_vX series has the RPM range extended and a bunch of other features. If you run N/A MAP then it would be the code to use. If you run boost MAP, then installing a 3 bar diesel sensor on ECM pin F14 and a small code mod. for fuel and spark to the AUJP will be much faster than looking into / documenting the $8B code. If you are just plain curious about the $8B then go that route.
