AtlantaZ Posted January 11, 2011 Share Posted January 11, 2011 Please contact me if you have a functional .MSQ configured for a fuel only N/A 280z(x) engine. Why? I'm trying to go about my engine swap in a methodical sort of way, meaning phased upgrades as opposed to the whole-hog approach. So for Step 1, I thought I'd go ahead and get Megasquirt II V3.0 running on my stock '76 280z fuel injected engine. After I get the fueling down pat, I'll move to a trigger wheel timing input to the Megasquirt, then full fuel-and-spark control using the Ford EDIS setup. But for now, I'd feel REALLY good if I could get Megasquirt to just run the injectors on an otherwise healthy engine! Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted January 11, 2011 Share Posted January 11, 2011 Do you already have the MSII? I'm selling my MSI v2.2. unless you'd like to assemble your own. I will work great on your na engine. Quote Link to comment Share on other sites More sharing options...
AtlantaZ Posted January 11, 2011 Author Share Posted January 11, 2011 Thanks for the offer! I do already have my MSII... bought it off a 240sx owner in my area. Do you happen to have some settings you wouldn't mind sharing? Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted January 11, 2011 Share Posted January 11, 2011 do you have the stim and tuner studio or megatune also? Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted January 12, 2011 Share Posted January 12, 2011 Other then for the constants, I don't really see a use in providing MSQs. Every engine runs different, and I don't like to think I could have helped blow up a car with my tune. That said, the startup, engine constants, warm-up stuff, etc, sure, but you can see those in the sharing sticky. For the fuel map, get yourself a wideband and familiarize yourself with the multiple ways of tuning A drivable map can be done in about 30mins worth of time.

AtlantaZ Posted January 12, 2011 Author Share Posted January 12, 2011 I have the stim and Megatune/TunerStudio. When I got the MegaStim board to make TunerStudio's gauges respond, I was like a kid on Christmas. I'd love to have an in-car LCD display so I could run TunerStudio fulltime with the gauge display! Regarding maps/MSQs: I'm looking for the constants like Req_Fuel, etc., and I didn't find much in the way of N/A settings. I assume there are a few differences. I was also hoping to find a ballpark fuel map that matched the N/A setup, then tune that. I'm really hoping to get the full version of TunerStudio and use VE Analyzer Live to dynamically dial in the tables! Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted January 12, 2011 Share Posted January 12, 2011 inj open time 1.0ms, batt V correction .20, PWM current limit 60%, PWM time threshold 12, required fuel 12.6 with 1 squirt. it will calculate required fuel when you provide displacement, # of cyl, injector flow rate, and desired afr.

AtlantaZ Posted January 12, 2011 Author Share Posted January 12, 2011 What about the cranking & warmup settings? Is there a recommended set of parameters for an N/A engine? Quote Link to comment Share on other sites More sharing options...
