The SCU doesn't offer any performance benefit. You need the Power Module for that. But the Power Module can't correct speedo error. You need the SCU for that. So you'd need both.

You get both functions with the Fastchip reprogram, and it's cheaper than buying both Jet units.

You already quoted Jet saying it does. Stop hijacking the thread if you're not interested in tuning.

Sorry, I thought you were the one that started this thread, with all the engine mods. If your car is stock, taking off the speed limiter isn't a good first mod. There's a reason for a speed limiter.

[/QUOTE]i'm not hijacking anything, but if i planned on adding a bunch of mods to my car, i wouldn't want some suped up honda civic to beat me just because i can't go over 115, just like Nikos95. i don't plan on taking the limiter off until i've done a few mods and i get z rated tires. so chill out bubba [img]graemlins/slap.gif[/img]

I've been running a megasquirt with my 3.4L for a year and a half. I'm controlling fuel and spark and I tune w/ a wideband O2 to get just the a/f ratio that I want under boost. I wouldn't go any other route mainly because of the price. I built my second unit by scrounging up parts and it ended up costing me ~$100. Of course you have to do all your own wiring and stuff but it's not that big of a deal if you know your way around a soldering iron and especially if you have a set of the factory manuals with all the wiring diagrams. Although I'm not sure what this would mean for an automatic car. I have a manual so I didn't have to worry about it. You might be able to keep enough inputs going to the stock PCM to keep it controlling shift points as normal. The megasquirt community is also working on a controller for the 4L60E so that would be another option.

Also, if you just want to eliminate the speed limiter you might be able to disconnect the speed sensor and use this to control the speedometer:

Although this isn't taking into consideration what the stock PCM needs for transmission control, and you'd most likely lose your cruise control. I took mine off long ago to make room for other stuff [img]tongue.gif[/img]

well i'll be the tester to find out what happens with MS and an automatic. i should know more this weekend and get back to everyone. if you look at the factory manuals everything should work fine except for maybe the TPS splices into the tranny controls. but again i'll know more this weekend. as of right now i know first and reverse work but i haven't driven it yet

**WNRacingICE** · 02-09-2006, 10:41 PM

You Can not disontect the speed sensor on the 93 - 97 Auto 4L60E. once you do this the car will no longer shift out properly. I know for a fact on 3.4 and on 3.8. We have done it a few times with the same results.

**WNRacingICE** · 02-09-2006, 10:46 PM

P.S. I Purchased a Jet Stage 2 Module and it raised my Governer. It has been awhile since i had it installed on the Camaro so i can not recall exactly by how much. You may want to look into it.

**Nikos95** · 02-10-2006, 02:10 PM

The JET SCU 2000 (Speed Control Unit) interacts with the vehicle speed sensor on late model GM cars and trucks. It allows transmission shift points and speedometer calibration for vehicles where tire size or gear changes are required. It also eliminates the top speed limiter in these applications. It simply plugs in to the transmission and is adjusted with the turn of a switch.

Okay no from the looks of it here,the governor is quite possibly controled by the transmission, being an electrical tranny, it is more than possible. Anyways I think it could be a cool add on, but I think I will just go with the TSP custom tune because I want this car to run right, and take full advantage off all the work I put into it. Thanks for everyones input, and that find was good. I just knew that the Stage 2 powerchip thats available doesn't affect the governor, they even come out and say that much.

**Nikos95** · 02-10-2006, 02:17 PM

erm then to come again if you take a closer look at JEGS.COM they say they don't make it for ealier than 1996, where you can simply use a hypertech.
