Re: Spark plug reading and timing advance

Oh ok. I completely misunderstood the write up and table when I first read it. Not sure what I was thinking.

This just clarified it for me....much appreciated

Re: Spark plug reading and timing advance

Ok, been playing around with timing and have a couple of questions. Roughly, what is the max advance I should be able to spec out with 92 octane with my engine (in signature). I set the timing table based on the MBT chart and I hear a decent amount of pinging between 3000 - 4000 rpm, but it goes awa...

Spark plug reading and timing advance

Ok guys, when I search for a chart on reading spark plugs, I am finding a lot of variation, or at least looks like variation to me. This is the first time I am actually trying to read spark plugs, so I attached a picture if someone could give some feedback to make sure I am on the right start.

Re: Adjust fuel with Fuel correction calc

ok, thanks. Had some time today to play around with it and I got it sitting really close and definitely within the range that you state is acceptable in the fuel write up. now on to spark.

Re: Surging issue

Yeah, it should be 0.172 on top cells. Isc duty is basically how much the isc is having to work to keep the car idling. It sounds like you may have the throttle stop to far closed. Log ispibr and make sure it falls within range. The idle write up is a really good place to start. Read through that an...

Adjust fuel with Fuel correction calc

Ok, before I adjust anything, I want to be sure my thinking is correct. I have been looking at my fuel and noticed I was still off some, so decided to go through the calculations for fuel error. What I have found is that up to around 1.8 MAFV, my error ranges from about 1.02 - 1.07. Once the MAFV ge...

Re: Cold/Warm Startup - Lean Entering CL

This change (bumping the niold to 1 and changing the hego switches to 8 instead of 3) seems to have fixed the issue I was having as well on mine when entering closed loop. I had bumped up the startup fuel to help the "puddlee" effect", but it was still acting a little weird at startup...

What is the best way to run a pcv system? I have mine set up as the original way on a 5.0 fox, or I think I do. PCV valve in the lower intake with a hose ran to the upper intake and a hose from the valve cover to the tube that is on the top of the throttle body. I think i am getting way too much oil...

Re: Starting out and moving on to fuel

Use commanded lambse as your guide since you don't have a wideband. Above 14.6 and you are rich. Below 14.6 means you're lean.

Lot of great help on here. Good luck and keep at it.

Re: Always lean after start up

Went through almost the same with mine. Mine would only stay lean for 10-15 seconds about 30 - 40 seconds after startup. Making sure the fuel was dialed in helped. I discovered that even a small amount being off with fuel dialed in made quite a difference with this issue after some guidance from dec...

Re: Spikes very lean after startup

OK, with that in mind, here's what I'm thinking. Would it be safe to command it to run rich for the first 60 seconds by using this table? Like 11 - 12 AFR at all temps, then drop the startup to all 0's in the last row. I just ask because I know you have said it can be harmful to an engine to run rea...

Re: Spikes very lean after startup

Ok, I was thinking FN1322 was in seconds, but it was confusing me a little since it said load on the y axis and the units is in seconds - FN1322 is the table I have bumped up. What exactly does these 2 tables(FN1321 and FN1322) tell the ECU to do to fuel?

Re: Spikes very lean after startup

Re: Spikes very lean after startup

It usually takes a few spins to fire up, about the same as it would take a stock mustang to fire up(not sure how else to describe it, just wanted you to know it doesn't take it an abnormally long time to fire). Is that still in the IEC crank duty?
