 Subject: LEASH< BG OR SUPERCHIP
IP: Logged
Message:
Frankly i still don`t know any numbers or graphs for these flashs, (Leash and bg).
Now that i`m ready for it, i`d like to get some info from those who have experiments with any or both.
I`m considering also, the superchip, advertised to produce around 20 20 hp and tork, on performance mode and stock engine. Its beauty, is in the fact that we don`t need to send the PCM to be flashed, and why not the other functions of it?
I have a 2000, 4.7, 5 manual, lsd, 2wd,w/ fipk2, fastman 68 tb, H.O. intake man. and cams, Gibson headers and single cat. back, 180* tstat, relocated fan clutch,(to basement), jet chip to be replaced etc...
Thank you all for your attention and time. Peace.

I have a 2001 jeep grand cherokee with a 4.7 v8 and I have been researching this topic as well. From what I have been told the superchips is decent for performance gains, removing some or all of the torque management during shifting, but is not as good as a reflash. The reflash changes the tables in the ecu similar to the superchips, but they can be more aggressive since the reflash isn't bound by any epa rules. Also the reflash changes the maximum amount the ecu can learn and compensate from the tables. B&G also told me they can tell the trans control module that it is a HO version which will shift slightly better, although I don't know if this is the case for your application. I have not seen much about the leach flash, if anyone can point me in the right direction for finding info on that or contacts it would be appreciated. If I am mistaken anywhere in the above post please let me know, this is just the info I have been able to gather so far.
Thanks,
Mike

Mine's '00 5.9, which may not be comparable, but I've had a Superchips and now have the BG.
I bought a used PCM off eBay and sent it to BG to flash, mainly to keep the old one for heavy-towing or if the cost of premium bankrupts me.
The Superchips gave a slight increase but didn't consider it worth the cost. Although the easy programming was nice.
The BG was VERY noticeable and I'm happy with it.
Easily the best and easiest mod I've done...and most $$. I paid $430 about a year ago.

I'd say SCREW all of that sh*t altogether.
There is NO REASON someone couldn't just as easily write software for a standard PC to do what the SuperChips programmer does and even more!!!
All you would need is a serial port (which is what the programmers use) and a PC, Laptop, etc.
I bet you some brains are doing this on OTHER platforms, (Honda's) etc. I haven't looked into them since I'm not a sh*t box Honda fan but I could only assume it would already be done due to the support.
The PCM in our vehicles would be no harder to program than anything else so called "Hacked" where you used an interface and software.
I've used (or at least heard of) similar hardware and software to program DSS cards, cell phone eeproms, you name it.
The big performance companies probably just don't want to do it this way because the data cable could be duplicated with parts from Radio Shack once someone saw one and the software shared over the internet!

Well I was searching around the internet.
Is DODGE really that un supported????
I found several places to get software for GM LS1 engines and similar. Not exactly anything real current however.
I just can not beleive it isn't being done.
It shouldn't be as hard to crack as what some people have cracked (smart cards, etc). But i guess money or at least the need would be the driving force.
That's kind of cheesy. But still would be cool to just plug it in and download our PCM's fuel and spark map's and whatever else can be altered.

Hey, if you can crack it, there's a market out there. I've heard its not easy to crack though; I'm still pleased with the Leach flash I got. Extra ignition advance, raised speed limiter, AC cutout at WOT.
Lead, follow, or get out of the way

I'm not a programmer. I can mess with small stuff like PBASIC with little micro controllers a little and have followed instructions using OTHER people's software (smart card programming, cell phone modifying, etc) but if they have cracked the PCM enough to have a hand held programmer change the mapping in the eeprom on those. Then they CERTAINLY can give PC based software to do that and so much more.
There just isn't PROFIT in doing that. Because with the hand helds they obviously VIN lock it to prevent from sharing so each buys their own. Where if it was PC programmable we'd be sharing software over the net!
Which is what I WISH we were doing, DANM IT!
I had a computer programmer friend who was taking computer science and all that. But lost contact with him since I moved down here. I bet he'd point me in a direction.
