This is a question in reference to a 5.8L MAF but i figured I can get a universal answer.
I'm ordering Trick flow heads, intake, exhaust etc... For my 351W this week, this whole keeping it EFI thing seems like a headache but for some reason i'm set on doing so. My problem is I want to run a pretty radical cam, and the manufacturer says I must get the MAF calibrated for there cam.
So my questions are...
Where do I get this done?
I plan on getting an aftermarket MAF anyway, is there a manufacturer that will sell them calibrated to my needs?

Also this is what I'm going to run
trick flow CNC 190 flow heads, roller rockers
trick flow box-r intake
90mm throttle body
bigger injectors
aftermarket MAF
long tubes

I figure the big intake and throttle body are a little much for the engine now, but i want it so in another couple months or so I can build a stroker bottom end with an aftermarket block and efectively use all the EFI and intake components no matter how radical i go from there.
Also I really just want it to sound like i just put all that money into the engine thats why i'm leaning towards a relatively radical cam.
Anyone have suggestions on a cam with a good sounding idle without MAF calibration?Or is there a magic number, such as stay less than xxx lobe seperation
I'm flexible on how the power hits . (not a drag car...not even a car)

 

what year is your pickup? AFAIK 88 was the last year you'd be likely to see a speed density setup.

If you have a MAF then the cam is irrelevant, you'll fix that via a software tune. If your ride is speed density, then you'd need to do a MAF conversion which is, yes, a pain in the ***.

 

It's a 96 Bronco, its definately MAF. Speed Density was found in pickups/broncos up until 94 and even some in 95.
How would I go about getting my software tuned?
JDM is very close to where i live, i know his father never actually met him but i imagine they would be able to tune the software. If you buy a Hyperchips Programmer, do they let you tune it on there or no?

 

K, you have a MAF setup then so the tune will be retardedly easy. JDM may be willing to tune it but I don't know... I've heard conflicting tales about what they will and will not work on.

Hyperchips is crap. Don't bother. SCT is my preference especially as the combo gets more radical. Diablo is favored similarly by many others. Hyperchips is not.

They'll need to put your truck on a dyno and either add a chip to the ECU's maintenance port or they can flash the ECU with a SCT/Diablo handheld with a custom tune on it. I would go the handheld route in case you decide later you want to adjust fuel or spark or gears for some mod or special occasion without the expense of a complete re-tune or any additional dyno time.

Total cost with the handheld for a proper dyno tune is usually around 300-500 bucks. Don't cheap out. I've given you THE way to do it. It costs a bit but it's right.

Hyperchips handhelds have canned tunes in them which are no good IMO. You want a custom tune if you've done that much to the motor.

 

OK cool, so the SCT or Diablo will let me custom tune it and change it later on. I appreciate the help. And thats the best way to do it is to get some dyno time?
I was looking around and saw a few programs, one ofthem being Sniper( http://www.rpmoutlet.com/sniper.htm ). Its software for your home computer which allows you to tune your car computer from there, for about the same price. Ever hear of this, would i still be better off with the handheld programmers?

 

I like sniper and a few others but that's really for someone that knows what they're doing and I didn't want to step you into something that's really a lot more complicated than most people are ready for or capable of.

Yes, get some dyno time and have the shop's tuner set you up a custom tune. Check out your shop before hand so you know they're packing the skills you need, JDM is known to be ok AFAIK.

I'd call up SCT and ask them what the most advanced handheld they have for your truck is and get that. The pushrod computers are an older generation than the modulars so they may take a different handheld, I'm not sure anymore.

No matter what though, CALL JDM and SCT (www.sctflash.com) and let them set you up right. I would consider any internet advice more detailed than what I've given you to be highly suspect.

For your cam, give Ed Curtis at FlowTech induction a call for a custom grind. The cost will be about what you'd pay for a XR series cam from Comp Cams. Determine your horsepower requirement, then use of vehicle...consider driveability as a "radical" lumpy cam will not idle well and buck at part throttle especially.

For your MAF and tune..Look at a FAST Classic system first, then SCT from a good tuning shop.
