Lime-swap.com PCM

[GarryM]

Wanted to give my feedback on another option for upgrading your H3 PCM. I had been reading and searching for more performance modifications for my H3. Came across Jeremy at lime-swap.com and he was local to me. Meaning I could stop over at his house and have my PCM reprogrammed. After talking about what I was looking for , stopped over on Saturday to have the PCM reprogrammed.

We had some issues with the bus shutting off and restarting so we decided to pull the PCM. Let's just say, pulling the 3 connectors on this module was a chore, and for a short person like me having a step stool is a must! Lol

The PCM was installed on Jeremy's bench and he started asking questions to confirm how I wanted the program setup. After reinstalling it, Jeremy hooked up his laptop and we drove the car to ensure everything was working properly. He will also adjust the PCM again for me when I get my 35" tires amd 17" rims.

Total cost was $100. Amazing price for the differences, the hummer is night and day difference. You can send in your module to him for out of state owners for the same $100. No I do not work for him, get kick back or anything. Just passing along this information as another option for H3 PCM upgrade.

Glad to hear the good results. Pulling the connectors should be easy (with a stool). Each connector has a safety pin or tether. Pull up the tether, pull up the latch. Should be a five minute task.

i would have thought , easy enough. Safety pin, and latch where the easy part. Pull connector from PCM was more difficult then thought. In the end it all worked out and I'm very happy with the results.

Willing to share his location? From the middle of the mitten so if he's local that may work for me as well.

He also used to be a great source for turbo exhaust manifold and injectors for our motors but I think he discontinued.

His contact information is on his webpage - Northville, MI.

+1 for Jeremy at Lime, he answered all of my questions, mostly on the weekend, and fit me in his schedule as I was in town for the weekend. I was pretty cool seeing what he does on his laptop. Anyways, the things I learned are:

-Jeremy KNOWS what he is doing, not just someone that dabbles with a laptop.
-for $99 you can't go wrong
-it's not about the horsepower, it's about the responsiveness-I can keep up with traffic now! Mine is set at 35% meaning it's 65% more responsive than stock. There's barely a delay when I hit the throttle.
-06 and 07's idle at 650 rpm. 08's and up idle at 600 rpm. Hence the "rough" idle. I had mine bumped up to 750 rpm, very smooth. This was after I cleaned the throttle body, replaced plugs and air-filter.
-Due to GM software, it is easier/quicker to tune 08 and up. Mine was done in under 1/2 hour and stayed in the truck. I believe Garry has an 07.
If anyone has questions, ask away. I had mine done in early November, no issues so far.

Thanks to GarryM for starting this thread!
