Ozzie831 Posted July 5, 2013 Author Share Posted July 5, 2013 Thank for the link. But unfortunately the only laptop i have is currently in california.... for a month..... but perhaps i can borrow my girl friends Quote Link to comment Share on other sites More sharing options...
Ozzie831 Posted July 13, 2013 Author Share Posted July 13, 2013 I finally got around to snagging a laptop. Again im a noob at this. Im sitting here running Tunerstudio and Im assuming since the RPM gauge is red, that means it's not reading the RPM haha. so yea no idea where to go from here Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted July 14, 2013 Share Posted July 14, 2013 You'll have 3 wires to the dizzy. 12v, ground and signal. The signal wire goes to pin 24 in the megasquirt harness. You should have a 1k 1/4 watt pullup resistor jumped across pin 28 and 24. Set fidle output to spark A. That will be wired to a GM hei module. The hei module will also require a pullup resistor. I don't know all the little details off the top of my head but all that info is here. Also use the link I sent you. Quote Link to comment Share on other sites More sharing options...
Ozzie831 Posted July 14, 2013 Author Share Posted July 14, 2013 Do I still need an HEI module if i have a 6al? I talked to a guy at diyauto a while a go and he said I didnt need one if i had a 6al. also i dont have any resistors so that could be another issue. Im also using a generic wiring harness from diyauto so idk if all the pins are the same, it also comes with a lot of wires that you dont use.

skirkland1980 Posted July 14, 2013 Share Posted July 14, 2013 I forgot you were using an MSD box. You still need the pullup resistor from 12v to pin 24. Just jump pins 28 and 24 with a 1/4 watt 1k ohm resistor. Your turbo dizzy will have 12v, signal (to pin 24) and ground. Get all that fixed and you should get an rpm signal. You need that before anything else. Let me know if you still need help after that. Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted July 14, 2013 Share Posted July 14, 2013 Here is the dizzy wiring. It's linked to the link I sent you. Quote Link to comment Share on other sites More sharing options...
Ozzie831 Posted July 14, 2013 Author Share Posted July 14, 2013 alright a little confuse. question one: Is a pull up resistor a separate component or is that the 1/4 watt 1k ohm resistor? question two: By you saying jump wires, does that mean that Im just basically bridging them with the resistor? since I dont have half the stuff on that attached thumbnail, Im even more confused haha.

skirkland1980 Posted July 15, 2013 Share Posted July 15, 2013 On your 2.2 board, turn it over so you see the soldered connections of the db37. Solder one end of the 1k resister to pin 28 and the other end to pin 24. On the diagram, tach is pin 24. Quote Link to comment Share on other sites More sharing options...
Ozzie831 Posted July 16, 2013 Author Share Posted July 16, 2013 Alright Ill give it a shot. I just dont have the tools to do small solders like that. I just have a cheap auto store iron haha Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted July 16, 2013 Share Posted July 16, 2013 Yeah, I paid $6 for mine. Quote Link to comment Share on other sites More sharing options...
Ozzie831 Posted July 22, 2013 Author Share Posted July 22, 2013 Well i got the resistor soldered on but still not getting the rpm signal Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted July 23, 2013 Share Posted July 23, 2013 It's wired exactly like the diagram? Are you reading any sensors with your laptop connected with tuner studio? Do you get rpm with a stim? You may want to contact diy tech support or open a thread in megasquirt subforum for more help, it request to get this one moved there.

Ozzie831 Posted July 24, 2013 Author Share Posted July 24, 2013 Again I have no experience with anything electrical or tuner related haha so all of this is foreign to me haha. Thanks for all the help though. Not having someone here to walk me through it is going to make this a long and frustrating process for both of us haha. I might want to try and take it to a shop and see if they can figure it out. I dont think there are any 280z megasquirt experts where Im at though haha.

skirkland1980 Posted July 25, 2013 Share Posted July 25, 2013 You could send me your distributor, harness, and ms and I could get it working and send it back to you. If you take it to a shop and say 'megasquirt' they'll say 'HUH?' Quote Link to comment Share on other sites More sharing options...
Ozzie831 Posted July 25, 2013 Author Share Posted July 25, 2013 Yea I know what you mean, no one really knows what it is. That is a kind offer, Im not sure if i wanna tear it all out again though. If there was a way that I could take photos, that would be cool. Quote Link to comment Share on other sites More sharing options...
