United Radio in Syracuse fixed my BCM computer and in 2 days and the set odometer correctly. They have a bunch of OEM computers in stock as they bought most of Chrysler's supply during chapter 11. If they can't refurbish or fix it they will give you a new one. The cost was $150 including S&H. The employees were very nice and knowledgeable. If they can fix you won't be charged.

SO.... if you notice the date when this topic was started on 8/7/17... That SAME day, I and 6 other Prowler owners from So Cal were on our way to Reno NV to get a look at Hot August Nights. We arrived in Reno Tuesday evening on 8/8/17 and when I went out to my Prowler Wednesday morning and started it up.... I had a Check Engine light. (Ugh!) The engine ran fine, I re-tightened the gas cap, but after driving to Virginia City and back, it did not reset. Later, when I finally got to Auto Zone, they checked for an Error Code and discovered it was P0601. It DID reset when I disconnected the battery... but it came back on after the second engine start. But it still ran fine all the way home (700+ miles) with NO other symptoms.

Thanks to this Topic, when I came home, I contacted BG Performance and downloaded their submission form and sent in my PCM (2001). They need the VIN and Mileage and to know of any performance alterations on the car.

I am happy to report that I received my PCM back on 9/11/17 and my Check Engine Light is OFF and my OBD Code Reader reports NO error codes.

I don't know the details but it is my understanding that their process Flashes the computer so that it is optimized for Premium fuel (which I was using anyways) and so the timing curves can be a bit more aggressive. There are other slight changes.

I have only driven the car 10 miles so far but feel that it is running great. Did I notice a difference? maybe....(more testing is in order)

(Full disclosure). The ONLY issue I see is that they must put a sticker on the PCM that states their name (BG Performance) and that it is for "Off-Road Use Only". The sticker can be removed. I will find out in December if this causes issues with getting the car smogged in California. It shouldn't since there is nothing they do from a programming point of view that would scream out that it is an altered component. (I will update this item when I know for sure)

I hope this helps someone in the future.
So far, I'm glad that I didn't have to shell out $2200 for a remanufactured PCM from the P... S....

Excellent Scott!!! There covering there back side with the sticker. BUT....you should still fly through smog check. Did you have them do any other mod's such as fan/temp control? Did they recommend any other changes? Please keep us updated after you have some miles on it as to your assessment regarding performance and anything else you think is relevant.

Wow your from my hometown, I was born and raised there. With the smog laws the way they are does this effect them in any way? What kind of extra horsepower do you get?

Hi, The turn around time for this service is pretty quick...I chose ground shipping, which is 4 days from California, and they sent it back via ground shipping as well. I think they had it for 2-3 days so that's a total of 11-12 days.

Forgiveness is against POA policy, lol. I am presuming that is the correct cost, but it could be diff. actually.

Well the guys at B&G know their stuff. Chrysler guys to boot. I would not want to send my unit to a generic shop to try and save a few bucks. B&G has been around for quite some time and has all the proper codes to access Chrysler systems.

As for how much HP. There's not a lot left in our systems that's waiting to be unleashed. When Chrysler designs these systems they have to be functional in Arizona as well as Alaska. Because we know that were not going to use the car in those extreme different climates, they can tweak the ignition and fuel curve and squeeze a little more HP out of it. I wouldn't think we'd see something that is a night and day difference.

SO.... I've put about 40+ miles (during 3 trips) on my Prowler following the PCM upgrade and I have to say that the car is running GREAT! I have 27K on the odometer now and it is completely stock except for having the baffles removed from the exhaust tips. It's hard to say if I picked up significant HP. Like many have stated before now, these cars were pretty well tuned to begin with. BUT, it still feels like there is an improvement... is it 8-10 HP? How would you be able to tell? Perhaps the RPMs simply get higher , faster and thus I feel a bit more Torque. But more Torque means more HP. It's hard to put my finger on just what is improved. We definitely need more input from other testers.

Other owners have been inquiring about a computer "chip" solution for years. I think THIS is the way to go. In MY opinion, this company should be placed under the Performance Topic so others can take advantage of their service.

Great to hear your having good luck with B&G. For people that don't know, there is no "chip" for Chrysler products. Chrysler uses speed density systems on their cars since the beginning of full computer control. The engines follow a built in graph that responds to certain engine perimeters. These speed density systems have been the bane of Chrysler products when it comes to engine modifications. The only way they can be changed is a program flash that will follow what mod's they have been instructed to follow. Ford and GM engines use mass air flow sensors which are far more favorable when it come to adjusting engine performance. And what's worse for Chrysler products is that every time you make further modifications you will need another program flash to accommodate new performance parts and how they affect the engines fuel and ignition curve. Since day one Chrysler has kept the pass words to their system under tight wraps giving outside companies the almost impossible task of cracking the codes. B&G has the goods to help.

BINGO-------Speed Density is not a 'user friendly engine control system'

While I can't argue that point, if I recall correctly I purchased a 'chip/ performance' upgrade in 1998 from Hennessy Motor Sports... I think that they offered 3 levels of upgrade...I sold that cat in 2001, but I think that I still have the Hennessy brochure in my Cat files.

UPDATE: I am happy to report that I passed my California Smog Certification TODAY. It's been over 1 year now that I've been driving my Prowler with my reprogrammed PCM from B&G Performance and still no error codes of any kind. The dreaded P0601 is gone for good!. (It still feels to me that the car is running better too!)
For more info see > http://www.bgperformance.com/

P.S. As it turns out...(in CA)... that for 2000 and newer vehicles many smog shops simply hook up the car to their computer and verify that ALL the sensors are installed and "SET" (i.e. working) and that there are no error codes set in the PCM. (The local Repair Shop in my town doesn't even bother with 1999 and older CA Smog Certifications anymore! They refer those cars somewhere else.)

Do they do Transmission and Body modules too?

How about the instrument cluster, this would take care of most of the hard to get electronics in the Prowler.

More modern cars have a lot more modules than the Prowler, aren't we lucky.
