Laptop+soft instead of ECU

Many things are possible.
Many things are also not smart.

Nah, LS runs on premium juice from the factory. I'd have to ask a few more questions of the tuner to get exactly what was changed, but he's tuned multiple different LS's, including his own one-off turbo kit, so he's no hack and he backs his tunes with dyno results.

A solid state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. An SSD emulates a hard disk drive, thus easily replacing it in any application. An SSD using SRAM or DRAM (instead of flash memory) is often called RAM-drive.

Again, WHY? Just cause? Do you really want to DEDICATE a laptop to running your car? Add weight to your race car? There are already very good standalone ECU's. If it's a DIY thing, get a MegaSquiitNSpark kit for a couple hundred bucks and build it yourself, or just download the plans and scratch build it. Standalone ECUs typically have their own FlashRam with enough space for datalogging.

I don't see the upside to lugging around a laptop in your racecar with an HD or SSD. Plugging in the laptop to the standalone ECU in the pits, yes.

Just cause you CAN do something doesn't mean you SHOULD.

shoult, I have to thank you, 'cause you mentioned * *MegaSquirt - Electronic Fuel Injection Computer by Bowling & Grippo * * - it looks like self made construction kit - but if I understood it correctly about a "half a car" should be rewired to make it work.. True?

So ANY standalone ECU is not a "plug-and-play" module into a stock socket?

Correct, standalones are DEFINITELY NOT PnP. Some are closer than others. Some require you to replace sensors with more generic sensors (usually GM style), others can work with what you have. It's been several years since I worked with them, but from a quick googling about it doesn't look like THAT much has changed. Typically the hardest part is getting the crank sensor set up. Oh, and deciding what type of fuel injection your going to run.

Why did I read the initial post thinking....this dude's running an OBD2 connection through a laptop.

EDIT: I've had mine hooked up a few times....to someone who doesn't know what it is, I can tell them I can control the AC with it

I was actually wondering if there was freeware to reflash my ECU.. i couldn't find any.. i figured there had to be some open source deal out there.. but not that I could find.. anyone else find anything? Btw my toughbook works great in my car rofl.. works great when i'm checking live OBDII data with it sitting in my engine bay..

what software are you using for that job ?..G

[c0alition]

was using a program called Scan Tool scantool.net had to buy an elm scan interface to use it.. but's it's the cheapest i've found so far.. now i'm using a program calld EasyOBD same features.. just not as graphic.

from SCT the pro racer package is real time tuning of the ecu through the xcal2 connected to a laptop? thats why i got it. dont have to keep on paying for retunes....
