Beater of the Pack Beater of the Pack Active BB Member Registered: 10/06/07 Posts: 2484 Loc: Northern Nevada	Not yet. I crawled around in the '89 & '68 some today. It was still too cold for me to be out there long, But I am making progress. I got the MSD wire harness for the "89. It is nice and will make that hook up a snap. When I'm ready. I'm trying to learn more about how Megatune works so I don't destroy what I have done. Is there a diagram that shows which wires on the GM plug are actually connected to the MS through the adapter? I did a little show and tell at our local meeting yesterday. There is quite a bit of interest. Tom _________________________ "I wonder if God created man because he was disappointed in the monkey?"

Beater of the Pack Beater of the Pack Active BB Member Registered: 10/06/07 Posts: 2484 Loc: Northern Nevada	I am ashamed to be succumbing to the panic. I just don't know how to make the '89 run without the ECM. I am worried about wrecking the MS. I'm trying to understand the tuning program. I put a coolant temp sensor on the '68 and the first nice day that I have off I'll pull a header and get the O2 sensor on. What if I did the ignition side on the '68 350 before I do the TBI? Set the MS up to run the spark with the MSD and the carb and then do the fuel? Beater _________________________ "I wonder if God created man because he was disappointed in the monkey?" Mark Twain

The hardest step is to get to idle as you have no reference to go from. Marc PS: you can always send me your MSQ file and I can have a look see.

Beater of the Pack Beater of the Pack Active BB Member Registered: 10/06/07 Posts: 2484 Loc: Northern Nevada	I know I can do it. I now understand all the steps that were holding me back. Each new step stumps me for a while. I know I'm closer to the end than the beginning. It's like Marc said, I do have a guy here running an MS on a 350. I could just copy his file and start there. It has been really nuts around here for the last month. I'm starting to catch up a bit. _________________________ "I wonder if God created man because he was disappointed in the monkey?" Mark Twain

efi-diy efi-diy Active BB Member Registered: 11/21/04 Posts: 1383 Loc: Calgary Alberta Canada	Tom, Remeber to warm it up on the stock ECM before trying MS and leave the set timing connector disconnected initially. Then all that is left is fuel to set up. If it will not idle on the stock ECM with the set timing connector unpluged - give the dist. a twist so you have say 10-15* timing BTDC initial. You can set it back later. Make sure you get RPM showing on the tuning screen. _________________________ 51 GMC 4.2 turbo Can't solved today's problems using the same technology/thinking that created them

Don't forget to set the injector outputs for Low Z injectors, the manual explains this quite well. I think the TBI 350 injectors are either 50 or 55 lbs/hr.

Beater of the Pack Beater of the Pack Active BB Member Registered: 10/06/07 Posts: 2484 Loc: Northern Nevada	I don't even have a file yet. That is what I'm trying to figure out. I can't tell what I need to change and what should be left as defaults for now. I'm going to see if ,Dave, the local MS user can walk me through it. I think I should just put away this MAC and start using Windows for everything so I can get used to it. My fear is that I will contaminate the whole Megatune program. I guess if I do I can uninstall it and start over. Tom _________________________ "I wonder if God created man because he was disappointed in the monkey?" Mark Twain

Beater of the Pack Beater of the Pack Active BB Member Registered: 10/06/07 Posts: 2484 Loc: Northern Nevada	A little progress. #1.Here I am using Windows. #2. I put a new battery in the '89 and brought it back up by the shop. It runs with the ECM timing signal disconnected. So now I need to build a file to use the MS. Actual use may be at hand. #3. I got the fuel tank etc. off of the '90 Suburban to go on the '68. Building a file and getting it on the MS is the last part that I have no experirnce with. Once that is done it's just car stuff, sorta'. $\:D$ Beater _________________________ "I wonder if God created man because he was disappointed in the monkey?" Mark Twain

efi-diy efi-diy Active BB Member Registered: 11/21/04 Posts: 1383 Loc: Calgary Alberta Canada	Tom, I agree that there is a LOT of info to sort through - since MS covers a LOT of different applications the info has to be there the problem is distilling it down to what you need. Some time I get bogged down in there too. At least I'll point you in the right direction to get your tune up ready: Follow the hardware and software configuration instructions for the 7 pin HEI ignition set up which is stock in the '89 - note you DO NOT NEED THE EXTRA RELAY SHOWN if your are using the GM to MS adapter board its built into the adapter board.. GM 7 pin HEI Idle air controller Follow the GM IAC wiring and configure instructions MS IAC fuel & injector set up You need to configure: [list] []req fuel [] low impedance injectors (TBI injectors are low impeadance) [*] The values shown in the manual for the TBI injectors work reasonably well and should allow you to get it started. Read this section on low impedance injectors and how the PWM works Low Z and PWM In megatune under tools set: the sensor calibration (MAP)to be: For the MPX4115 use 10.6 and 121.7 <<< same as a the GM TBI MAP sensor. Set the thermistor table for both the coolant and MAT sensor to be GM - use the pull down menu to get the value populated into the tuning fields automatically. Since your running an innovate wideband calibrate the AFR table as wideband, innovate 0V== 10.0 AFR, 5V == 20 AFR Then before you start and after you have the MS connected to the truck under tools open calibrate TPS - with the throttle close click get current beside the closed throttle box, then mash the throttle to WOT and hit the get current beside the full trottle box WHILE you have the pedal mashed down. _________________________ 51 GMC 4.2 turbo Can't solved today's problems using the same technology/thinking that created them

Once this and the PWM setting are right your alomost ready to start. _________________________ 51 GMC 4.2 turbo Can't solved today's problems using the same technology/thinking that created them

Beater of the Pack Beater of the Pack Active BB Member Registered: 10/06/07 Posts: 2484 Loc: Northern Nevada	Yes, It was good to be right there with someone who has done it and actually use my stim, MS, & laptop. He was able to clear up a lot of little things that were keeping me from being able to follow some of your hints. As has been my biggest problem all along there is too much information, at least more than I need at this point. It's really busy here right now. We are moving the water from one of the springs over/through a hill and I'm trying to get my runaway horses back from wild and free roaming herds of the of the far west. Maybe next Sunday I'll be ready to try and run the '89. I can at least play with it now with less fear and get in the settings in that you have sent. It was a good day and more of it makes sense. PROGRESS! Thanks, Tom _________________________ "I wonder if God created man because he was disappointed in the monkey?" Mark Twain

It ran when I put the stock ECM back. I've got stuff today I'll put the stim on it tonight or tomorrow and make sure it's OK. It was a rush thing today and I should not have tried it at all but the sun was shining and the wind was less than 50 mph. It started then died. I think it was with left over fuel.

Make sure you fully warm the engine up on the stock ECM first. Also make sure you have the injectors configuration set up for low impedance injectors. The manual goes into detail on how to do this. You can also send me your tune up file and I'll have a quick look see. The bonus of TBI is you can look and see if the injectors are spraying fuel while your cranking. After you check all of the above, I'd do this next - it'll tell you right away if you have a fuel delivery problem. efi Edited by efi-diy (05/03/10 12:08 PM) _________________________ 51 GMC 4.2 turbo Can't solved today's problems using the same technology/thinking that created them

efi-diy efi-diy Active BB Member Registered: 11/21/04 Posts: 1383 Loc: Calgary Alberta Canada	Tom, Warm the engine on the stock ECM disconnect the set timing connector and using your timing light adjust the distributor so its running around 20* BTDC base timing. Leave the set timing connector disconnected until you have the idle/low speed fuel set up. Plug in the MS Crank and see if you are getting fuel sprayed, if not check on the laptop if you are getting RPM displayed. No RPM means no tach signal ->> no tach signal means no fuel sprayed. The tach signal is what triggers the whole meal deal. If you don't have a tach signal you have something mis-configured and you MUST fix it - nothing will work until you do. Also the fuel pump will not turn on past the inital 2 second prime period unless you have a tach signal. - you may need to open the throttle a bit while cranking - it may take some diddling to find the right throttle position where it will start and run the first time. The amount of fuel injected during cranking is controlled by the cranking fuel pulse width ONLY not by the fuel table. - once it starts, if its lean you may have to keep stabing the trottle to activate the "accel" pump. - if its rich generally the engine will run but you will know if its burning your eyes out... - as soon as it keeps running say at 1200 RPM open the 3D VE MAP (fuel table) and move the red dot using the arrow keys to where the engine is running indicated by the blue dot. And then either richen or lean the fuel until it idles - remember to adjust all 4 corners around the operating point. Then let off the throttle a bit and adjust the next operting position. Repeat this process until your at curb idle and the engine will idle normally. the Q key richens the fuel the W key leans the fuel Also remember that if it floods open the throttle past 70% and crank - if the throttle is open more than 70% your in clear flood mode. Almost no fuel is injected. As soon as it catches let off or it will die from no fuel.

Mean buzzen half dozen A.K.A. Hank Mean buzzen half dozen A.K.A. Hank Active BB Member Registered: 09/23/04 Posts: 4544 Loc: Ca	For all out HP,they(carbs or EFI) would be about the same. For drivability,& produce more mid range torque,usually the EFI will shine over a carb set-up. I think once you get used to EFI & is set-up correctly,,changes will be much easier,total timing control + fueling . No arguement from me,carbs are easy for me also. You can see how Beater is having a hard time w/this,but if someone was there to show him how to do it, I am sure he would catch on right away. Once he gets comfortable w/the megasquirt,he will make changes much easier. I would be in the same boat as him w/the megasquirt,I would probably fly some megasquirt guru over to my house & teach me & be done w/it. MBHD _________________________ 12 port SDS EFI

There was very little help around for DIY EFI except that odd person on the MS forum. Tom Email me your tune up file I'll look and see if there is anything off. Did you disconnect the set timing connector? Can you see fuel being sprayed while cranking?

And yes I can tune a carb reasonably well. When I can move a fuel or timing value 1% and find power that would take a well equipped carb shop equipped with a wet flow bench to do, its hard to beat. If your coming to Texas next month you may be able to see it first hand. _________________________ 51 GMC 4.2 turbo Can't solved today's problems using the same technology/thinking that created them

I can also tune carbs. I just thought this would be fun. It might still be. $\:D$ I'll have help tomorrow. At least someone to turn the key while I check some stuff. Yes, the timing is disconnected. The closed reading on the TPS was 108 and not 0. It may be held open with the set screw. I'll check that.
