For two thousand and twelve some makers are introducing direct fuel injection on gassers. Hyundai and honda are two that I am aware of. This does improve fuel milage a noticable amount. All engine builders will have to follow this lead in my opinion.

My VW's got direct injection, along with a 6sp its fun. Also got 39.6 mpg on a long highway trip the other day

Not sure it would be worth it to do in this setup. Still, I'd like to see how well it works out before I buy into it. In the diesel world, they introduced the 6.0 VT365 to replace the 7.3L T444E. It did contribute to the breakup of the Ford-International romance. Problem was people were so in love with it and later on, they were trying to trade it in for something else. T444E units became much sought after after that new technology failed to deliver. Those that traded their T444E units regretted it. Till it goes on for a few years without issue, I would consider it experimental.

Not sure how to adapt it for this but it would be interesting.

Mc mega sqirt is for the un-informed. I never understood why its even mentione here knowing the extreme frugal nature of the benz crowd. a Junkyard GM 730/ and v8 harness would be a much better choice.

haha you're funny.

Thanks, as far as the DIY/EFI guys there are two different factions. McMEgaSqirt and the guys using GM junkyard stuff--and neither can understand why the other likes his best, I know one reason ---GM computers are the best there are, and a $75 setup in the hands of someone who knows what to do with it is much more versitle than a $750.00 mc squirt. If someone waned to run forced induction-its easily doable now that a computer is controlling knock-rather than old days carb setups. that intake looks like it could have been modified by Tull industries in san antonio Tx

The official gm turbo computer is a 7749 Sunbird, Syclone ecm--and theres a more advanced custom writen -code 59 done by some technically inclined syclone guys. a 749 is very hard to find and a user can much more easily get the 730 and run code 59 on it or even a military spec "hardened 727" corvette ecm that can live under the hood of a hotrod.

Theres a 88 sunbird at the copart auction for junk price in Madison Wi right now. I just scored one when I spotted a sunbird sold at the copart in new braunfuls Tx, I had to weasel the info from a copart gal and then go to the yard in SA TX where it was sent.

From the pictures it looks like the swap was done well.

Do these GM computers do multi port batch, sequential and semi sequential injection, multiple fuel maps with self tuning, closed loop WBO2 control at any AFR, coil on plug ignition, water and nitrous control, VVT maps, lauch control, traction control?

the 749 will do all of these things- cretain models will do the waste spark coil pac type ignition, the user would have to then rig a crank sensor instead of a distributor for signal. And either peak and load or low resistance injectors it has two drivers, as far as the last three you listed or four I doubt any mc squirt guys use any. im sure some of the syclone crowd water injection.

It seems traction and launch control are the same thing, That would have to go in a car--a very new one that has the ability to have the axle/s controlled. not many enthusiests got something like that, maybe you are doing a mc squirt tour-de-force to, overly hype the sQuirt. But ill definately say you know more about tuning computers than I do-for Sure.

I dont even know what VVT is-ill do a search-But im still learning this stuff and its a steep learning curve, Everyone says Mcsquirt is a little easeier to use than the GM stuff -there are a big sqirt geek cult-but I dont think that much if at all really.

a prom emulator-> ostrich<- from moates will let the user have multi prom switching capabilities, as well as on the fly with only the single prom

I guess VVT is a newer obd2 terminolligy, all the popular gm obd1 ones allow the user to do custom mapping--there's a different version of the 730 that's got 2k more ram that I just heard about -I guess to go in and have finer map tuning capibilities between points.
I got all kind of info but wont violate the copy and paste copyright rule.

Was I mistaken about the price of the latest-gREATEST Mc-squirt?? is it north of $750.00 ??

whatever I need to do can be done way cheaper-perhaps wit a few add on gizmo's Ill pick up a WB o2 tuner-second hand from some ricky racer honda kid.

Wow I didn't realize the GM ECM guys had such an inferiority complex about Megasquirt. I certainly don't get off on putting down other engine management systems (except maybe Kjet). If you like that GM ECU use it, more power to you. Personally, I read up on GM 1227749 ECM and I wasn't terribly impressed. As far as you cost claims, I have $350 in the MS1 setup and $500 in MS2. Do what you want with those numbers. I like Megasquirt because it was cheap, easy to install, easy to tune, has a active community that helped me on many occasions. The EXTRA firmware has gone through many generations and its become very intuitive for newcomers. I've helped several people in the MB, BMW and Volvo communities setup their cars and made some good friends in the process. My MS1 car has 20k miles on it and passed SMOG twice now, MS2 has 10k. Its been totally reliable thus far. Its taken me from San Diego to BC and many points in between.
cheers

I wouldn't call it an inferioity mentallity, We just dont think there's much chance its superior to what GM spent all that money on --and that-bowling and grippo are sticking with the original plan of keeping prices low. A tidy wiring harness without all the extra garbage is really the only advantage i can see, and as i said--You definately know more about tuning than i do, but like anyone drawn to a certan faction, they read what they WANT to read in all the info to help ---Feel Better---
about their expense.
Perhaps.

Maybe I'm way off but getting EFI + WBO2 on the road for $350 doesn't seem that bad to me. Load free MS1extra firmware, free tuner studio and free MLV and I really doubt you're going to beat that deal with the GM ecu. If you don't like the price of the B+G kits, used MS1 controllers are showing up ebay and CL all the time or you can even grab one of the knock off controllers. They still work with the same firmware. Again, if you like the GM ECU, use it, I just don't see a compelling cost argument here.
