efi-diy efi-diy Active BB Member Registered: 11/21/04 Posts: 1386 Loc: Calgary Alberta Canada	I needed somewhere to hang 2 more injectors/hole and the stock intake being plastic doesn't take to well to tig ... Once the boost is >7psi the fuel controller will taper off the pump gas (stock injector location) and start injecting 100% methanol. At 9 psi the gas injectors won't be fueling the motor as the fuel will come from the 2 horizontal methanol injectors. Normally you want the injectors to spray the back of the intake valve to get good vaporization, under boost though the air is hot enough to vaporize the methanol which will cool the charge air. 8 PSI on gas was fun, looking forward to turning the wick up... toward 20 $\:\)$ <<< go hunting for LS6 powered vettes.. _________________________ 51 GMC 4.2 turbo Can't solved today's problems using the same technology/thinking that created them

Just remember, Methanol's some pretty toxic stuff (have a read of the MSDS if you haven't, makes MEK look downright civil). Not as bad as Propylene Oxide, or Hydrazine, but not good either. _________________________ My, what a steep learning curve. Erik II#5155

mujgy mujgy Bulletin Board Only Member Registered: 12/31/08 Posts: 1 Loc: north dakota	I've read up on your build pretty freaking awesome. I've got a 48 Chevy truck waiting in the wings maybe I'll drop that new 4200 in there. I checked out your YouTube video too, say those are s10 wheels, that isn't a regular cab s10 chassis under that body is it? I've measured it out at its really close and is what I'll likey use when I get going on this project. I really like how the truck looks without running boards and in flat black. Keep up the good work!

This replaces the VVT drive to allow aftermarket sequential engine management to get a off/on cam sync signal using the OEM cam sensor.

efi-diy efi-diy Active BB Member Registered: 11/21/04 Posts: 1386 Loc: Calgary Alberta Canada	MS testing time... I'm doing some garage testing too.. got a couple of items to test and sort out: Completed - 1) a new MS3.0 Main board & MS2 processor - works on the bench ok - going out to plug it into the truck. Completed - 2) convert to MS2extra code... still using ford EDIS module and EDIS coil pack. #3 Completed... I'll post a quick video later. It took a couple of good backfires until I sorted a wiring issue out $\:\)$ BOOM BANG BOOM Then fixed it and hit the key - instant start! Much less cranking than when I'm running the EDIS module. 3) then convert to direct fire (coils fired directly from Megasquirt without the EDIS module) the coils - 3 pairs of 2 coils - coil on plug but wasted spark mode using the 36-1 timing wheel pick up that now triggers the EDIS module reconnected into the new MS box so I get direct timing input - fire the motor and set the base timing. This will prove the ability to fire the stock GM COP coils. On to the the biggie.. I sent the engine timing diagram tonight to the software dude to get an idea for an initial setup.. hopefully by tomorrow I have an answer. Then out to the shop to test... more BOOM BANG BOOM WHOOSH flame... I'll install the MSextra test code into the new MS box - connect one coil (#1) with a spark plug just grounded on the outside of the motor, so I can get a timing light on the short plug wire between the coil and spark plug. I'll connect the new MS box to the GM crank trigger sensor. Then I'll re-connect the original MS box installed running the ford EDIS module with the timing control input to the EDIS box unplugged I'll get fixed timing at 10* BTDC. Then I'll run the motor on the EDIS box and orginal MS box - check the timing using the timing light to see where is its at. With the engine running I'll try and get the MSextra test code triggering off of the GM crank trigger to sync up and fire the one coil at the right time - I'm guessing it'll take a software fix or 2 to get it right. Once all is good then I'll connect the new MS box with the MSextra beta test code up to all 6 coils as in #3 above and run the motor off of the GM crank trigger and the 6 coils in wasted spark mode. What this will do is free everyone who wants to run this motor from the GM electronics ( and Westers Garage choke hold on modifying the stock GM electronics) and eliminate the need to install a custom trigger wheel. the only mechanical mod will be to install cable type throttle body. This will bring the cost of conversion down a chunk. A pre-built MS that will run this motor is pricing out about US$400. Once I get this s/w tested I'll be able to supply a good tuneup file for the MS that folks can install (its easy - if you can open a windows file and click 1 button in the s/w your good to go). If all the wiring and fuel supply is good turn the key == brummm.

As time goes on I understand more and more of what is being said about MS and electronics in general. You are really making the 4200 a more viable choice.

efi-diy efi-diy Active BB Member Registered: 11/21/04 Posts: 1386 Loc: Calgary Alberta Canada	The GM trigger is still not proven as I write this. I was triggering the MS off of the 36-1 trigger wheel that's mounted on the front of the crank. The 36-1 wheel drives the EDIS system. If your in a hurry I'm have a 36-1 trigger wheel setup on order for the turbo motor and can increase the qty. Direct cost from the CNC shop EDIS wheel = $350 ea Support Brkt = $125 ea Standoffs = $60 for 4 The reason why I'm still adding a crank trigger wheel is this: I'm testing a beta version of the sequential system and it need the 36-1 trigger wheel to run it. The MS sequential system does not support the GM 7 notch crank trigger found on the 4200 (if you managed to find a 2007/08 motor then it does as the later motors use a 60-2 trigger like the LS series engines). Its a s/w thing. Eventually it will happen.

Its nearly the same configuration that we ran last year on the Black Opel on the salt so I would not see any issues with the install. The only difference is the Black Opel used the EDIS coil pack instead of the COP coils - the result is the same. I actually loaded the Black Opel tune up file to get the ignition parameters ( just quicker) then overwrote the Opel's fuel and spark table with my own from the stock turbo motor. With the EDIS system the engine cranks a lot longer before it fires, I was surprised how fast it fired up! _________________________ 51 GMC 4.2 turbo Can't solved today's problems using the same technology/thinking that created them

I've been slacking a bit on my 4200... but want to get it going again... Still need to get the internals going, but ecu for me at first is most important... and as of now, it looks like I'll probably have to go for something like AEM full standalone... just because people know them etc... pretty common.

I do not know want a mega-squirt is.Please define. I am also having difficylty locating Metric bolts that do not cost an arm and leg plus my first born, any ideas? How much help would a factory manual be? I was "gifted" and '04 4200 from my son. It is from a Olds Bravada. Will this still work, or should I be looking for a newer one? Is there going to be a kit that will put this thing in my Sub without recreating the whole thing? '49 Fleet '49 Sub _________________________ Inuke

efi-diy efi-diy Active BB Member Registered: 11/21/04 Posts: 1386 Loc: Calgary Alberta Canada	The 4200 needs an ECM (engine computer) to make it run unless you want to go through the exercise of building a carb manifold and adapting a distributor. If the engine is complete with the COMPLETE GM harness including the stuff from under the dash and you have the GM ECM then use it. Megasquirt is an aftermarket DIY ECM http://www.msefi.com As for metric bolts mcmaster-carr. Or the wreckers. The '04 will be fine for what you want to do. No kits - its all scratch build. _________________________ 51 GMC 4.2 turbo Can't solved today's problems using the same technology/thinking that created them
