Megasquirt tune files, request to post .msq files Options

[Rikyrat]

EGADS, tuning my megasquirt fi system, is driving me nervous.

If anybody has and would wiling to share tune files with me, I would be very appreciative. As that would allow me to compare it with mine

Thank you in advance

Here's my tune on my 1.7. It has a longer duration cam, CB independent throttle bodies, Triad exhaust, trigger wheel, and waisted spark. So it is just a reference but will probably not do you too much good. However the Base tune that was on the microsquirt when Mario sent it out to me had the car running and idling out of the box. Mario (The Dub Shop) was able to log in to my computer remotely and finalize the tune on the dyno for us. Great guy

Thanks for the tune file. I am running the dub shop setup with CB Performance ITB's and a MSDS header on a stock 1.8, building 2056 motor is next task on my list.

The base tune from mario, got me running, but it still has a long way to go.

I am puzzled about the ITB's and the Kpa, I seem to be idling at about 50kpa, does that sound right, per your experience.

Did you or Mario set the req fuel value to match your displacement?

Assuming Mario loaded some sort of base config on there and its not just the stock Megasquirt config, stick with the msq Mario had on there as he knows what he is doing as far as setting up all the base settings. He may even have a more accurate fuel and timing map for a stock 1.8 if you ask him.

Provided the req_fuel value was set properly the only part of the tune you should be tweaking at this point is the fuel map and possibly the timing map (depending on how Mario set those)

Importing timing and fuel maps is a safer way to go as they are independent of your specific hardware and the full MSQ file and good timing maps for type 4s are going to roughly all be similar.

Post your current timing and fuel maps and I could give you a rough idea if something is obviously out of whack. Other than that, if you have it started and idling you should be using your wideband sensor and autotune or datalogs to dial your fuel map in.
