Anybody have experience with these ? I tuned my ranger when I had it it worked well especially helping a little bit with the mpgs. I was thinking of getting one for the van for that one purpose but now I,d like to try to calibrate the tire size so I can possible get true mpg readings. Anyways I found this SCT SF3 model 3015 on eBay..... Let me know what you guys think
Not nearly enough info to really answer your question here Sir.
Depending what motor you have Mike @ 5 Star tunes is da man for the V10 and V8 guys. He's very, very represented in the Modular Motor forums. Go there and you'll see either a sticky thread or something in the appropriate tech folder.
He means 460.....and I don't think so as far a pure Tuners go....
Okay---that was my first thought about the CID.
No nothing much in the ECM tuning is available for that era motor. There were or are "chips" that somewhat easily replace the factory EPROM, more designed for high performance rather than having the ability to act as a 5 Star tuning program functions.
I mean no offense, but millions of people have put larger tires on vehicles throughout history and continued to drive them. Including people who have put 33" tires on Toyota pickups that were designed for 25" tires without thinking about it and continuing to drive them until they were junk.
You have a van with 150k miles on it and to save yourself the trouble of adding 4% to your gas mileage calculations, you are proposing some kind of $400 reprogramming gizmo. You will NEVER recapture any significant cost of that programmer. Just add 4% to whatever mileage you might calculate and call it a day.
If I had any clue you would have been this concerned about your gas mileage calculations, I would have strongly pushed you to stay with your stock sized tires because it seems you are really troubled by this. I would suggest you save the $400 a programmer would cost you toward the cost of gasoline or for your next vehicle. Or for only $100, I can teach you to add 4% to any number on a calculator or spreadsheet program
(And I apologize in advance for any smartass tone that this post might have...really, just drive the van and worry about real life issues.)
The 225 to 245 tire change is not enough to bother with a reprogrammer. Those vans in the short body version came with 225s, the extended version sported 245s. If you want a tuner for fuel mileage and performance gains, I highly suggest a SCT SF3 or X3 tuner with custom tunes by 5 star.
4% is nothing. I was getting just under 12 mpg before (around town+occasional highway).... now i am not even 10 according to my calculations. I think i have to add about 75 miles to a tank mile totals and that give me my true mpg's. 4% is not accurate its more like 20%. but besides that your right, who cares if its off, the van is riding great, especially in this snow up here in CT this winter w/ the michelins.
Never heard of a 7.5 V8, never heard of any 7.5 gassers either!
Come on JWA, you know a 7.5 is a 460!
There's not gonna be much out there tuner-wise for a 460 unfortunately. Most of them were pre OBDII which became standard in 96 and by 97 I think 460s were replaced by V10s. Someone correct me if I'm wrong. I have a 95 that I would love a 5-star tuner for but I'm stuck with intake/exhaust mods only for the most part, unless you really want to hot rod the thing.
Scotty ya know the more I read here about the 460's they seem to be somewhat of dogs when installed in a truck or van. Of course I'm probably comparing them to their high performance Boss motors used in cars way too small and light for that much power. (Being a closet Chevy performance van a 427 or 454 in almost anything GM made in those days was too small and too light too!
I can't see most of us needing a high revving motor for our daily commutes or work vans though. Its a seductive thought but the cold slap of reality tends to kill the allure!

My 97 e350 is a 460, and I have no issues with the rancid MPG numbers. It's bad, let's just put it that way.
I'm interested in a tuner/programmer because I'd like to wake it up a little more. It made a big difference on my old 98 Durango, which I know the van and the rango are completely different animals, but with no changes other than the programmer, I was able to pick up noticeable power, a little MPG, adjust the transmission shift points, adjust the speedo for different tire sizes, tune for performance, towing, etc. It'd be fun to be able to play with the van that way too.
The ECM of the 460 is OBDII, it isn't programmable, you need to put a chip in it, the 97+ can be tuned, I have my 99 E350 5.4 done, it's one requiring high test gas, does not improve mileage, gives more power and performance, the reprogramming of the transmission prolongs it's life. Combine this with intake mods and exhaust, you can increase gas mileage, if you can keep off of the throttle.
FYI the 460 ceased after 96, replaced with the modular engines, 4.6 V8,5.4 V8, and 6.8 V10, the only engine that continued service was the 7.3 powerstroke.
