taylor76zharris Posted January 11, 2013 Author Share Posted January 11, 2013 Okay ill see if i can post my msq as soon as i get home Did you verify that Q16 is there? Take an ohm meter and ohm pin 7 on the 40 pin cpu socket to the left pin on the bip373. You should have 330 ohms if D14 is your spark output(preferred). You can also ohm the middle pin to the coil neg. and the right pin to ground while you're in there. The middle pin of bib373 to coil neg? should i get the same ohm rating of 330?

skirkland1980 Posted January 11, 2013 Share Posted January 11, 2013 You should have very close to 0 ohms. Link to comment Share on other sites More sharing options...
taylor76zharris Posted January 12, 2013 Author Share Posted January 12, 2013 I was confused on this a bit. B/W and G/B both have a 12v supply but the G/B wires 12v supply has a 1k 1/4 watt resistor in it? Why is this needed? Link to comment Share on other sites More sharing options...
skirkland1980 Posted January 12, 2013 Share Posted January 12, 2013 It's a pullup resister to produce a square wave output from the turbo dizzy. Link to comment Share on other sites More sharing options...

Why is this needed? Pull up resistor gives you a path to power the optical circuit inside the dizzy and limits the current to the optical diode inside the dizzy so you don't melt it. You can put the resistor inside the ECU. Link to comment Share on other sites More sharing options...
FricFrac Posted January 15, 2013 Share Posted January 15, 2013 Well something got fried. Right where it says IGBT on the back and q16 on thr front. Im not sure why it happened Did you make sure you set the dwel for your coil and inverted on the coil output in the software? Link to comment Share on other sites More sharing options...
taylor76zharris Posted January 15, 2013 Author Share Posted January 15, 2013 okay. Ive been doing lots of reading on drop resistors latley and i think im finally understanding what there for. Yes, it was set on going high inverted but my dwell setting may have been wrong. What should my dwell be set at? Im using the stock coil and a stock 83 turbo dizzy. I cant remember what my dwell was set at, its been so long. Link to comment Share on other sites More sharing options...
skirkland1980 Posted January 15, 2013 Share Posted January 15, 2013 Something like 6 for cranking and 3 for running. Are you getting an rpm signal when cranking? Link to comment Share on other sites More sharing options...
taylor76zharris Posted January 15, 2013 Author Share Posted January 15, 2013 Okay, i think mine was set at 9 for some reason. Yeah i was getting an rpm signal when i was cranking and i know i had fuel. The coil just wasnt releasing a spark i think, even though it had power to it. I really need to get the system wired back in the car. Ive learned all on here in the off season. Link to comment Share on other sites More sharing options...
skirkland1980 Posted January 15, 2013 Share Posted January 15, 2013 That's a lot of dwell. The bip373 will really heat up. I read they are supposed to shut down if they get too hot but mine started smoking also. I don't think it 'shut down'. Link to comment Share on other sites More sharing options...
taylor76zharris Posted January 19, 2013 Author Share Posted January 19, 2013 lol. I hope mine did! Alright ive almost got it all wired in again but one thing i noticed is on the megasquirt unit there is a bar map sensor inside. Do i connect a vacuum line to it? I did not realize this the first install but it has a nipple on it and theres a hole on the side of the megasquirt ecu. Link to comment Share on other sites More sharing options...
loy Posted January 19, 2013 Share Posted January 19, 2013 Yes, A source from your intake manifold. lol. I hope mine did!

taylor76zharris Posted January 24, 2013 Author Share Posted January 24, 2013 Alright awesome. There were a few things i overlooked the first go of this install, so i think ive got everthing corrected. one thing that is concerning to me now is wiring the 12v drop resistor. I dont want to splice into the wire because i dont want to chance it shorting on the shielding or another wire in the shroud. Whats the best way to go about wiring it in? Where should i connect it? Thanks. Link to comment Share on other sites More sharing options...
skirkland1980 Posted January 24, 2013 Share Posted January 24, 2013 You must already have it wired in since you're seeing an rpm signal. Link to comment Share on other sites More sharing options...
taylor76zharris Posted February 2, 2013 Author Share Posted February 2, 2013 I do now yes, just at 200 RPM. I still have no spark. Im pretty sure everything is set how it should be. Im using direct coil control and my board is set up with all the proper jumpers per DIYautotune for direct coil control. All that can leave is the coil, ive got the +12v and the - to pin 36. the coil is getting power however, megasquirt isnt able to finish the circuit somewhere and release a charge.

skirkland1980 Posted February 2, 2013 Share Posted February 2, 2013 Can you take a picture of the front and back of the board and upload your msq file? Link to comment Share on other sites More sharing options...
taylor76zharris Posted February 2, 2013 Author Share Posted February 2, 2013 Ill have to upload my msq file a little later. Im having trouble getting it to work. Here are some pictures though. Hopefully you can read everything. Link to comment Share on other sites More sharing options...
taylor76zharris Posted February 2, 2013 Author Share Posted February 2, 2013 Could i just take a screenshot of all my tuning tables open? I cant seem to get the msq to upload Link to comment Share on other sites More sharing options...
loy Posted February 2, 2013 Share Posted February 2, 2013 (edited) Where are you checking for spark at? At the coil? plugs? Edited February 2, 2013 by loy Link to comment Share on other sites More sharing options...
taylor76zharris Posted February 2, 2013 Author Share Posted February 2, 2013 I have been checking both places, coil and plugs. I even bought a new coil thinking that might be the issue. The ignitor on the coil bracket, i have nothing wired to it. i didnt think it was used Link to comment Share on other sites More sharing options...
