Jacob Ochs Posted September 5, 2016 Author Share Posted September 5, 2016 What part has you stumped? It took me a little while to grasp tuning a Megasquirt. I did a lot of reading and talked to guys who had done it before before I really ended up getting it.Well I have it idling... somewhat so when I plug the MAP vac hose up to the megasquirt it revs up to 2k and wants to idle there but when I take vac off it wants to idle somewhat normal..

Jacob Ochs Posted September 8, 2016 Author Share Posted September 8, 2016 Radiator shroud and fan made, in the process my impatient self poked a hole in the radiator core. :( But I have a lifetime warranty on it so I'll have a new one in the 13th!

Sent from my SAMSUNG-SM-G890A using Tapatalk Is this only when it is warmed up, or at any point? what happens when you start it with the map connected? Same thing or runs normal?

HOrnbrod Posted September 9, 2016 Share Posted September 9, 2016 Are you using the correct GM MAP sensor for the 3.4 turbo? Check the voltage outputs. Does the Megasquirt massage the voltage outputs like the Unichip does? I know zero about the Megasquirt system..... Link to comment Share on other sites More sharing options...

The megasquirt has an internal MAP so I just ran a vac line straight to the megasquirt to avoid any problems like that Sent from my SAMSUNG-SM-G890A using Tapatalk Link to comment Share on other sites More sharing options...
Megadan Posted September 9, 2016 Share Posted September 9, 2016 what do your O2 sensor readings look like when the RPM shoots up? go rich, lean? Timing changes? The problem with Megasquirts is that there are so many modes you can run in, that it requires asking a billion questions to figure out something simple.

I'm starting to think my base timing is way off.. I'll check tonight! Sent from my SAMSUNG-SM-G890A using Tapatalk Link to comment Share on other sites More sharing options...

Sounds like either an input parameter is off on a sensor, or you timing or A/F maps are off. Playing the the VE tables is always fun. IMHO, I would go through the initial startup procedures on Bowling Grippo's website like this is a first time start and double check all you settings one at a time. It's tedious, but it will help narrow down the problem Link to comment Share on other sites More sharing options...
Jacob Ochs Posted September 14, 2016 Author Share Posted September 14, 2016 Installed the 97+ washer tank for a cleaner engine bay look and ordered a 850ml coolant overflow tank. I'm ditching tuning it myself and found a tuner in St. Louis for 600-$900 and I'm happy with that. So on goes the project!

HOrnbrod Posted September 14, 2016 Share Posted September 14, 2016 Suggest you install the other pump in the washer tank and run the fluid hoses and wiring into the engine bay and cap them off. 'Cause when the single washer pump craps out (it will, mine did) you have to pull the fender liner, etc. to change it. With the 2nd pump plumbing and wiring in the engine bay it makes it a lot simpler. I'm all for saving myself unnecessary work. :yes: Link to comment Share on other sites More sharing options...

Jacob Ochs Posted September 26, 2016 Author Share Posted September 26, 2016 Down pipe fabed up and installed, now waiting on a intercooler to come in the mail then that will be all plumbed up then off to get a tune.

Jacob Ochs Posted October 3, 2016 Author Share Posted October 3, 2016 Relocated the fuel feed and return lines because they were touching the exhaust and the last thing I want going down the highway is this thing catching fire. Progress is defiantly slow but sure. I'm dropping it off for a Tune on October 9th and he's keeping it a week then we should be fully functional!
