I have a 1998 ranger with 3.0 and I just installed the Jet MAF and my truck doen't idel right and the engine pings under acceleration? Then my check engine light came on! I called Jet tech support and he said that it was normal and it will go away after 100 miles or so! I just don't want it to harm my engine! I would really appreciate any info on these MAF sensors!

 

For one, there is no way a stock 3.0 needs a bigger maf. Unless you have a turbo or super charger, you'll see no performance increase. I put a jet chip on my 99 f-150, it cost me a 500.00$ computer. I'm not a big fan of jet, I can't say it will hurt your motor, but I can say it won't help your motor. Try resetting the computer, pull the positive cable off the battery for about 1/2 hour, reinstall and try it. I would tell you to get your money back, but since the part has been installed, I'm sure they won't. Also find out what code it's throwing from your check engine light. If the computer won't relearn on it's own for the bigger maf, you may need to get a bama programer from www.jusnesmodified.com. I put a maf on that same f-150, it caused a lean condition, I wasn't going to try another jet chip, took it to the shop, they finally got it running right, equalized the air, fuel ratio, but there was no increased performance.

 

I thought about your situation a little more, pinging isn't good, just like running lean isn't good. I don't want to see you hurt your engine. If resetting the computer doesn't help, can you put the stock maf back on ? If so, put it on and call or e-mail Doug at www.bama chips.com, and ask him if he can do a program for the larger maf. I would also try and find out if the jet maf isn't malfunctioning. The maf I had was a gms and it needed a program, there was no bama back then, so the shop reprogramed the computer to except it. It seemed like a waste for just a maf, so I installed a larger tb and intake as well, then headers and a catback. It took a few trips to the shop to get it dialed in, it ran good, but the performance was disapointing compared to the money spent. I tried again on my present ranger, but this time had Doug program me up a bama and this truck runs like a scalded dog compared to the f-150. This time I didn't use a bigger tb or maf, the stock tb is 65 mm and can handle all the air that my motor needs with the mods I have. Larger mafs intail bigger injecters, poted heads, larger valves, bigger cam, or forced induction. I don't know what you have done to your motor, but I dout you needed a larger maf. It's to late to cry over spilled milk, so I hope you can get it running right so you won't have totally wasted your money. Try the computer reset first and then go from there. Good luck and let me know how it works out.

 

Return the JET! Granatelli and Pro-M have both stopped making MAFs for the rangers, since they had a bad reputation for giving unstable readings. Put the stock MAF back, the only time a 3.0 needs a larger maf is when its boosted, and even then, whipple uses an OEM 4.0 MAF.

 

Thats what I think as well Bob, but will they take it back after it's been installed ? I had a granatelli, the shop got it running good, but it never ran great and the jet chip I had burned up my computer to boot. I dumped so much money into that truck, ended up trading it off. My ranger has turned out alot better with not near the mods that I ended up putting on the f-150. My ranger would have out run it. I learned alot from that experience. It would be nice if they would give him his money back, then he could spend it on something that works, like bama !!

 

Possibly, there is always ebay.

 

Well guys it is not a stock 3.0 I have JBA headers,high flow cats, true dual 2.25" strait back no mufflers, MAC cold air intake, turbo, Helix throtle body spacer, underdrive pulleys, removed fan& fan clutch and installed electric fan, cam and SCT programmer with 4 programs stock,87 octane,91 octane and 93 octane! each one adds more HP! The only bolt on mod I didn't have was the high flow mass air flow sensor and they claim you will see bigger hp gains with all the other mods I already have! I hoped it wasn't overkill and that it would give me a little more HP but if it isn't going to run right I will probably return it or sell it! I just wanted to see if anyone ever had any luck with the MAF upgrades??

 

turbo, true duals, and intake? Those mods dont add up. As long as youre not boosted, you dont need a MAF, period. Your engine will only take in so much air without being force fed, even with all your mods. If you WERE force fed, then the kit you used should have come with a larger meter.

I dont know who has done your tuning, but BamaChips will tell you, if you have an aftermarket MAF on a ranger, ditch it. They wont even attempt to tune it, even on a dyno.

 

with all those mods before the maf, was there any big improvement with the 3.0, i have same truck and just wondering cause stock 3.0 sucks in power

 

Best bet for power on the 3.0 is a BamaChips custom tuner. Then I would say an underdrive pulley. Intake and exhaust give marginal gains on a 3.0, but, it all adds up.

 

I would say the easiest way to make power on a 3.0, would be some sort of forced induction, the other route would be to flow the heads, up the compresion, cam and so on. 3.0's aren't noted as performance engines, there's not a lot out for them. For a slight bump, I would say Bob's sugestions are on the right track. It would be interesting to see some dyno numbers on jdhudall truck to see where he's at with those mods, he may be on to something. The worst part about it is, you could put 3,000.00$ worth of mods on a 3.0 and still not have the power of a 4.0 sohc. I think ford would be better off loosing the 3.0 as not to keep torturing people with trying to get more power out of them, no offense .

 

We do have a factory refurbished Whipple 3.0 kit with ported lower manifold and BamaChips tuning available. If youre seriously interested, contact me about it. That would make some power

 

Yes I have seen a major improvement over the stock 3.0 both torque and HP acording to my G-tech I went from 130 hp to 195 hp but all the mods are $$$$$ spendy!
