Its called Pulse Width Modulation and many factory EFI system incorporate this. I believe late 90s mustangs used it too.

What do you have to do to take an older TPI, or TBI computer to convert it to EEPROM? When I say older I mean 86-95

396375 Installing an EFI system is fairly easy if it is new and complete.Installing a factory system on a vehicle that never came with it is tougher but still doable.Trouble shooting and tunning is a whole new deal and not for the first timer.
MSD has a new system that dosn't require a return fuel line.The fuel pump pulses!The new kits are getting better,cheaper and can handle more HP every year.

I agree.
I started with TPI to wet my feet and next will be an LS1 ECM running sequential EFI on a BBC. Hopefully I will learn the tuning too using HP Tuners.

I think alot more guys are looking at it these days.

I think it is just the timing of Hot rodding of the past and Hot Rodding of today finally coming together!

4 Jaw Chuck It is changing, hotrodding is ever changing. Nice to see prices coming down for items like programmable EFI...and great guys like the mods in this forum to help oversee a place to discuss how to implement it.

EagleMark Hot Rodders is a dieing art with the youth of today. They are following the lines of new technoligy.

So that leaves mostly the older guys who have been around while Hot Rodding was High Tech! But the older guys are usually just not computer literate and some don't even want to learn? They would be shocked into learning if they could get to a site like this!

I'm an older guy (51) who got into computers around the same time EFI was coming into play 1989 and have combined my love of cars, Hot Rodding, and todays hot rodding, EFI !

If it wasn't for this section I would not have found this site! So I am glad it was added. Some EFI is simple to learn and old Hot Rodders have no idea how easy.

I think it is just the timing of Hot rodding of the past and Hot Rodding of today finally coming together!

Totally agree that the tech lines can be horrible, but I just want to set up the "situation" you are in once you dive in to diy efi. It can make you feel pretty stranded at times hunting for information.

the only megasquirts that are smd is the fully assembled smd versions(i.e v3.57 units).with the exception of the ms3 and ms3x expansion board these are addon boards that u cannot build urself.
these are nice because if u want to change ur ignition system input or add boost control u only have to move some jumpers around on the board instead of adding jumper wires and resitors.

the smd units are basically fully optioned out of the box


the diy units all come with a bare pcb, cpu and all the resitors chips capacitors u need to build the board urself in niceley labeld bags

an assembled ubnit is typically about 100 bucks more then a diy unit u solder together urself while i enjoyed building my first ms unit ms1 v2.2, the added cost of just buying a completly assembled and ready to go unit is worth it


as stated above deff go with a v3.0 board the boards are more heavy duty on th epower sides and can handle high or low impediance injectors without mods and when used with an ms2 or above cpu can control stepper motor iac valves.

the v3.0 board can use any of the ms cpus ms1 ms2 ms3

id also buy one of there wiring harnesses, the wires are nicely labeled to were they go every few inches down the wire, makes it really hard to miss wire something. not to mention trying to build ur own harness sucks when trying to solder wires to the db37 connector pins

396375 I have an Eprom burner and blank chips cheap if anyone is interested.
12-16-2011 11:17 PM
EagleMark Same thing, just differant way of doing it. Like a PC or a MAC.

If you already got a Megasquirt I would not try and talk you out of it. They are excellent. Just not the only avenue...
12-16-2011 08:21 PM
ap72 Seems like a lot of complexity and cost when ms1 will do the same thing? I'm just trying to figure out what the best approach for my project is.

EagleMark The Ostrich is an Emulator. You hook it up to your laptop and have your bin file open in TunerPro, load to Ostrich and it runs the car, make a change and save and it's Real Time. When done though you still need to burn a final chip or leave the ostrich hooked up forever?

I went with the AutoProm years ago and never looked back. It will Emulate like the Ostrich, Record data from engine like a cable so I can tune real Time, then burn the chip like the Burn 2 when done.

Go one step further and get a wideband O2 sensor and controller and you can wire that into your AutoProm and the AFR data comes in same data log as engine data in TunerPro.

TunerPro is easy to learn but then it is toatally custimizable as well, the more you use it the more features you find and learn to use.

That's the way I went. Didn't want to mess with the UV light so I went with the Eprom. I think they also have something you can piggyback on where you don't even have to remove the chips (or it replaces it and takes up its socket). They used to call it the Ostrich or something like that?

EagleMark Well the cable is cheaper than that...
http://www.aldlcable.com/

You have a laptop, software is free but has a nag screen at beginning and we all do try to pay for it so it keeps getting developed by a software programmer Hot Rod Gearhead so $40. That is asking price and removes 10 second nag screen at beginning. If you compared it to equivalent OBDII stuff like EFI live or HP tuners etc... for $1000. and then $100 per vehicle license fee, I hope you and anyone else who get's it and tries it supports him so this software keeps improving! Right now it has been about a 10 year project that keeps improving. It even does Holden, BMW, Saab, Volvo and even the Harley Buell motorcycle and keeps getting better.

Man I find so much cool stuff here, I've been a gearhead/hotrodder my whole life and have done so much in the past I find on this site today. Been on specific forums for years but never found this one! And it is way cool!

It's hard to believe you guys haven't got into this GM ECM stuff yet?
