pinging on 87

I'm not a hard core tuner (yet). But I've spent a good 50-60hrs tuning my ranger now. A good 2/3rds of that was tranny related too. Prior to this tuning software I purchased, I've used MANY chips and flash devises (like the Diablo predator & the SCT X-cal 2) over the years. And even in the ranger realm I've used tunes from three "tuners". (Bama, Henson, & Lasota) My experience is limited to either old school carbs.. or OBD2 The OBD1 stuff (1995 and earlier) I'm really not familiar with.

So.. if there is anything you guys would like to know about the stock ford tune.. or what a guy can change with a "tune"? Please use this thread to ask!

Also, I'm not selling anything. Even if I could make and sell tunes.. it would cost you more than going to an approved tuner. So.. I don't tune for others. Just myself.


For example... A open air filter. What effects does this have?
Well.. from a tuning perspective the stock ford tune for my 2006 4.0L starts to decrease timing at 110F temp. The IAT sensor is in the MAF sensor which is about 4-6" down stream of the filter. So.. just adding a conical filter that's open to the engine room heat (w/o changing the tune) very well might decrease power because of underhood temps and slow vehicle speed.

Questions?

Regards,
Rich

The OP hasn't logged onto this forum in over 2 years. You don't need to post the same issue all over the place.

2011 Ranger 4x4 Auto Tuning Question

Good Day

I just received 2 custom tunes for my 2011 Ford Ranger, a 91 Octane and 87 Octane Tune. I specified the following options to the tuning company:

All options open
Converter lockup at a user selected speed
Transmission gear selection criteria/shift points at a user selected speed
Fuel options to improve startup and drivability, ie startup
Any additional options suggested

Seems like I received all of the options that came with the downloaded canned tunes from SCT and not the additional ones I specified. Is there any reason why? Is there a way of gaining access to those options? Is there a reputable company that will give me a tune with the options I require for a reasonable price? Both of my tunes cost me $250 Can.

Any advice would be greatly appreciated.

Adjusting Automatic shift points and Converter lockup

I have a SCT X4 with both SCT 87,91,93 tunes in addition to a 87 and 91 Custom tunes for my 2011 Ranger sport ext 4x4 4.0 Auto. Am trying to figure out where the settings are to modify shift points and converter lockup. Unfortunately all of my tunes don't have this as a user adjustable option. The only thing adjustable transmission wise is % shift pressure at various gears and WOT. Any ideas would be greatly appreciated.

2000 ranger gem module questions

I have a 2000 ranger. The truck cane from the factory with 3.0 and 2wd. I bought the truck from some kids 3 months back and transmission went out. I got a ahop to rebuild it . When i got the truck back that night reverse went out. They came back and got it and fixed it. But the truck wont drive. So i had then tow it to a ford dealer for a 2nd opinion. Ford is telling me its the gem module. My question is when they put the 4.0 4wd in the truck what type of electronics woukd of been changed? Could this be the reason the transmission went out? What gem module doi buy one for 3.0 becuase im assuming mostly everything else is stock... or doi go with 4.0?? It seems to me like someone did alot of work t change over the wngine and transmission. Not sure why but im in to deep with this truck..any advise

What do you mean the truck won't drive? My guess is since the transmission was fixed that it is not the transmission. Please explain.

I can put it in drive and jt will ide all day long but when u go to accelerate it wont go over 2000 rpm. Ford says the trucks computer thinks ts goibg 100 mph and shuts off.does this sound right. In just out of money to soend on this damn thing

Did this happen since the transmission was fixed? If so I would check all connections to the transmission including the speed sencer on the transmission tail shaft in case the wiring was damaged during removal/installation. If you don't find anything have the Ford Dealer reflash your pcm with a stock tune in case something has been changed from the Transmission shop.

So what you are saying is you bought a 3.0 2wd that has been updated to a 4.0 4wd by the previous owner? If that's the case than they probably used a downer truck and swapped everything over including including pcm and in some cases wiring harness too. If they kept the 3.0 rear end there might be a conflict with gear ratios, pcm says one thing and diff says another. I would chat with the previous owner to get a feel for what was swapped and what wasn't.

It would seem that depending on the year of the doner veacle a Gem module is used, after that a powertrain control module and pats module would do the same job. If it has a defective Gem module it may need programming or a proper replacement as the Ford Tech suggests.

You may not be able to find one in the scrap yard as they are matched to the veacle, but check with your Ford Tech and see if one can be programmed to your truck and key set if you are using pats from a similar year as the doner. If so it would save you a few $$ as brand new they are worth around $600. Might be cheaper for a 98 Ranger 4x4.

I don't think so, but to be sure discuss with your Ford Tech. He will let you know if it will run without and what needs to be done to integrate in to your Truck.

Is there another way to supply power to the windsheild wipers beside going thru the gem module? Mine went bad and its unplugged and the truck runs fine.just no wipers. What can happen if it stays unpluggedand i keep driving. It runs fine. Shifting is better than before need to know any possible concerns

If it is pinging with no codes that means it is leaning out, would check the usual things air filter, plugs for too hot for the application, dirty Maf senser, plugged fuel filter and vacuum leaks.

My gem module is bad thats why i disconnected it . I have serched all over the counrty for one and cant find one. The dealer said that it woukdnt hurt anything if it was unpluggged. Now the wipers dobt work. The seatbest chime was going off before but aince i unplugged it its not. The speed sensor didn't work before. I just need to know if it stays disconnected is there anything damage that can be done? And is there an alternative power to windshield wipers

The only thing I can suggest is to talk to a Ford service rep locally or and see if it won't cause any more issues if you run your truck without, if not mabe cut your losses and sell your truck.

I have a 1994 ford ranger 4.0 4X4. factory 1" lift with 31's.
I am thinking about doing a few things, headers, exhaust, CIA, oversized throttle body & spacer, and injectors. If i do this in stages, would i need to tune/ retune after every mod?

Can I use a sct x4 tuner to shut off my egr or do I need to get a custom tune to do that?
