Megasquirt Project, .....IT RUNS ! Options

[Michelj13]

Hi,

Although I have been a member for a while (since I purchased my 914), I have not posted much. I still love my 914 and it's is interesting how this car drives like an absolute go-cart.

Anyway, my engine is a carbed 2270 that I built up with the help of many including Jake, and I am now embarking on a Megasquirt project. As many know, megasquirt is relatively inexpensive for a programmable FI system. I find, however, that there is too much information out there that it is nothing short of confusing. I want to share my progress so that at the end of the day, some may learn and may become less intimidated. Hopefully I will be successful....we'll see.

I have so many questions that I will post, along with some things that I have already learned. ANY and ALL comments appreciated.

I made a youtube video of my progress up to date. Enjoy!

Glad to hear you found the vacuum leak. did this help your MAP reading at low rpm? I suspect so.

The car should be easy to tune now.

If the car wants to die during off-throttle coast-down you need to check the decel fuel cut limit. raise the rpm limit a few hundred. You can also add timing to the lowest bins in the table at idle.

Don't forget that the stock MAP and rpm values rarely match each engine. Adjust these to match the lowest MAP reading in the second or third row. Then scale the rpm for your idle and redline. Then start tuning the engine. No sense in having rpm values to 7000 if you redline at 5500. Also, stop the MAP readings at 100kPa or close to this. No need to go higher unless you are running boost.

btw, if you are getting shocked then you might have a ground issue. Check the ground from coil to ground and plugs as well. You should not get shocked. It also could be that the wires are not seated properly at the plugs.
