what kind os soft ware would someone recomend for tunning the 5.0 in my 90 f250

 

No need for a chip here.. or 1.7 rockers if you select the right cam... you seem hung up on getting a chip.. is it for bragging rights or something? If so just lie and say you do if you feel it's necessary. Stock 5.0 intake is more than sufficient too, and no it cannot be combined with the 5.8 intake they are very different internally. I'd suggest you port match the lower to the heads though, this seems to be a common bottleneck on factory intakes.

 

Well the problem with the older speed density truck is they aren't really supported by the mainstream tuners like the Tweecer, you have to get into the mass air trucks or the mustang systems before you have something that is truely plug and play. I can plug in a laptop and monitor and change all parameters on my truck, but it's cost me $1500 for a MAF conversion and the tuner software to get to that point.

 

its not that i want the chip, because i of sure dont want to pay the price. but i was told that on a speed density truck ,if i change the cam and heads and all that prefornace stuff the computer wont know how to react and not run right?

 

Are you going with the SD or mass air ?? A store bought chip wont do much good . Im talking about a dyno tuned chip . It can cost about 600 but its worth ever penny of it .They put your truck on a dyno & go thru everthing to see how much they can get out of it . Set your timing curve & air fuel ratio & everthing you can think of & if you have an auto they set your up & down shifts . Then they burn you a custom chip for your truck .. You just got to find a real good tuner . The mustang guys are good at this & know how to tune a 302 ...

 

tuning the sd or mass air. summit will tune a chip for my sd for about 400 but you just tell them what you have on the truck and what you want it to do over the phone.

 

sorry i didn't chime in before i must have missed this thread but i take my stock bottom end 302 to 6k almost every other day or so, but it has stiff valve springs and a big cam so i'm not floating the valves or running out of power

i'm not sure why everyone wants torque in a 302, as long as your not towing anything and your truck isn't a pig then i would do what i did and just build the motor for high rpm hp and put a high stall converter in it, if you have an aod the converter locks out in 3rd gear and od so you can run as high as you want with out worrying about overheating the trans on the highway but if you put the right gears and converter in it i wouldn't worry about low end torque

not sure what conanoski has to say about this though lol

i don't think i've ever built a torque motor other than just putting a rv cam in an otherwise stock motor but even for the motors in mud trucks i build you try to get the highest h/p at what ever rpm it will come at and you don't worry about the torque just stick a high rpm stall converter in it or drop the clutch at 4500 or so and if your truck is heavy then put a heavy flywheel on it to keep the momentum going when you drop the clutch

i agree with portmatching the lower intake to the upper intake and also portmatching the intake to your heads and porting the heads out a little and smoothing out the bends

and if you want to get really into it you can get a crank ground for cleveland bearings which are bigger and reduce bearing surface speed but you also need to get your mains bored to accept the bearings

i would suggest getting a book off ebay on building smallblock windsors i bought one (forget who wrote it) but it was a great way to get some knowledge on the strong and weak points of these motors

 

I dont know how they can tune a chip over the phone.. 400 ?? Just find a good tuner or if you got the money like Paul just get the tuner like that then you can tune on it any time you want .. Lew

 

they just said they need to know the cam degrees and if i have headers and what not and they will make a chip that will run right with the cam and the adjustmant of air flow in preformance parts

 

where do you put this chip? replace the computer?

 

I say yank out that 302 and drop in a SBC. It's the cool thing to do.

 

i guess it plugs into the comp on the truck. and its for speed density. i have seen things online about taking a mustang computer and harness and wiring it into my SD converting it over. anyone know if this is a hard task?

 

They make a mass air conversion kit for the mustang . The harness is 60.00 the computer is about 350.00 & the meter is about 250 . Thats new . I have never done the conversion & not sure if this is all you need . some one will chime in thats done it before. Lew

 

The chip goes between the computer & harness plug . Depending on what kind of chip you can change what you want . Lew

 

A chip ordered over the phone really has no chance of being any good. The vehicle has to be strapped on a dyno with wideband O2 sensors and somebody has to look at all the data coming from the computer to see what the motor needs and then make appropriate adjustments. This is exactly how it's done with a DIY tuner as well except you drive it around the street instead of on the dyno.

If you listen to the advice you have been given here you won't need a chip, and you can get more power out of the SD system, just don't go too big or use a radical cam.
