For years I've been reading forum debates on MAF over SD in the 5.0 conversions. I live in the foothills of the Rockies at 5000' and every time I take my rig out I go to at least 9000', often 10K+. I don't make it down to see level often, but I'd like to be able to without having issues. My question is can the SD setup be calibrated to roll with these changes in altitude and temperature (sub-zero to 100+), or will this require MAF? Why? Every topic I've read on the subject seems to reference further mods, as if HP was the goal. Who can say HP is a BAD thing, right? But this is not a Mustang. I'm not going to the drag strip or even a strret race! I'm shooting for a solid 300 horse, but torque and drivability are my main objective. At this stage of my build I have:
73 Bronco
Built 302W block out of late 60s Mustang, 11:1, mild cam, installed EFI out of 88 T-Bird (speed density unit with white (I believe 17#) injectors), mated to a new NV-3550, and (not that it's really relevant, but... )rebuilt DANA 20 w twin stick, D44 front w discs, BB9" rear, 4:11 gears on 33's. Once built, I have no plans for further mods to the engine or drivetrain. Just wanna drive it! I'm not building a "rock crawler", but a daily driver I can take camping/fishing and mudding, jeep trails etc. Go around the rock for God's sake!
I plan to purchase an A9P ECU, harness and 19# injectors. My understanding is that you can run the A9P (for auto trans) with the manual trans, but not the other way around. Reason: I've also heard the A9P features more aggressive programming than the A9L to compensate for the sluggish AOD. If this is inaccurate, please correct me. Before I start that whole thing, I need to determine if I'm going MAF or sticking w the SD setup, as I will need an 89 or later ECU and a MAF setup, diff harness etc... Basically, I don't have $$$ to burn on MAF if I don't need it, but will not hesitate if required for ultimate drivability in my environment. BTW: Does anyone know a good tuner in N. CO?
Also, if there are any obvious oversights or potential issues w my current setup or plans (A9P + 19#), I'd like to hear about it. Thanks for your feedback!
