i was wiring up some driving lights on my truck, and found a PAC chips tuner plugged into the ecu.

I tried to find their website, but it seems to be long gone.

I pulled it out to get a look at it, but put it back in. can i run the truck with out it?

or am i now missing a factory piece?

Does anyone have any information on it?

I never really would have thought the truck was tuned, since a friend of mine has the exact same truck with the diablo in tune tuner, and that has crazy power compared to mine

 

That is old school!!!!!!!!! assuming it is like the rest...yes, the ECM still has the oem programming, etc and the "chip" was in essence an interface type device used to change the parameters.

 

I will try it without the chip and see what it really does.

does that handwritten code on the sticker mean anything?

 

That's most likely the specific programming code used by them

 

SOMEONE TELL ME WHAT CHIP WOULD WORK WELL WITH MY V-10 IN A 2000 RV.

 

Here’s what I would suggest you need to know. With regards to “Chips” and “Tuners”, years ago it was the best that most could do to enhance the ignition timing, fuel curve, transmission shift points, etc. It is important to verify the “Tuner” is ASE certified in ECM & Trans programming & current. Plenty of persons advertise their programs to be the best & offer custom tunes, but very few have credentials in these areas. Some of these “geniuses” have caused damage to a few vehicles- just jump over to flatratetech.com & read comments from the MSE techs!
Roush Dyno Tune Posted August 26, 2012
Bad situation-Need help! - Vintage Mustang Forums
To make an extremely long story short. I need someone to tell me who to talk to for help. I have posted several times and got a lot of help. Got my engine build finished in May. Ran great. Took it to Roush Racing for a tune. It is a 93, efi, 302 with several upgrades. Went to get it from Roush and the water hose had blown and torn up my brand new hood I just had painted. It can be fixed. Drove the car home and it would not start the next day. Finally found the adapter between the TPS and painless harness was missing. Fixed that. It would not idle consistently. Took it back to Roush. They said it was fixed. Went less than 1/2 mile and it was idling at 2500 rpm. Took it back. They were lost. I need help. I am totally disgusted. If you need to talk, PM me and I will give you all my personal contact info. Thanks for any help. I am out of options.
Perhaps what is equally important is the parameters that can be adjusted are set by the OEM vehicle software…so there is really no “magic” in what they are doing anyway. If you look at the dyno charts from many of these supposed HP/TQ increases, they are typically around 5%-7% at peak rpm ranges…….guess what, 5% is a standard deviation even amongst mfg dynos and if you go to this link http://www.fordracingparts.com/downl...ceTechTips.pdf the engineers at Ford racing have a article on just exactly how these “tuners” play games with the hp/tq ratings, how calibration can cause misleading dyno results, & some of the “tricks” that are used to gain supposed power increases when in fact, managing your engine….. and the most important item is……these “expert tuners” (at least most) do not have or choose not to test their results (in comparison to the oem intakes) during actual vehicle motion (or simulation- such as a wind tunnel) as the oems do nor are these "mail order tuners' regulated like any other auto repair shop in the US...so if they "damage" your car...gee, sorry...sue me!

IMHO, if you live near any major city there are excellent tuning specialists with dynos who for the same price (if not less) will tune your vehicle taking into consideration your specific needs including environmental conditions, for your specific vehicle. IMHO, the best bang for the buck!

If you are comfortable and understand how to tune a vehicle, you can also do this yourself. There are several software programs available, that “Speak Common English” that will allow you to tune your vehicles ECM. One company is HP Tuners, they have a website….they offer two core programs, one for those who are doing dyno tuning and one for the home-garage mechanic (which is priced at about the same as most of the “canned tunes on the market) …this version limits the span of adjustments as a safeguard against doing something outside of the oem scope……basically, keeps you from doing something “too stupid by accident” (grin) and Sniper Delta Force Tuning Software.

If you are set on purchasing a chip, I would recommend Blue Oval Chips....the gent (at least use to be) have Ford credentials and has been in the business longer than anyone else that I know of....specific to pre-OBD II ECM's.
