If this is a brand new TwEECer, all 4 positions will need to be downloaded. If you only downloaded your default program to one position, then flip the dial to another, that would explain your pump running constantly. When I 1st installed my TwEECer, all 4 positions ran the fuel pump constantly until...

Pro-M is better than C&L so this may not apply. However when looking at a "Stock A9L" which is the factory Mustang 55mm MAF vs the C&L 73mm using the clear tube (calibrating the MAF for 19lb injectors), there IS a difference in the curve. The C&L 73mm w/clear tube is a leaner curve (more air per vol...

I think I found what was causing my cold-start sputters. The low slope injector size value needed tweaking. I have 19lb (orange) injectors on the engine. Like all injectors, they get sloppy when their pulse is very small...as is the case during idle and crank. When injectors get sloppy, they are slo...

My heads are stock, but they are stock GT40p heads which were better than the stock E7TE heads. They have smaller CC chambers (59cc) and an altered sparkplug angle to allow for better burning and swirl. Perhaps my heads are enough better they can handle additional EGR gas? The EGR did do some good. ...

Right now, I'm not concerned at all about WOT. I put a nice WOT advance in and it doesn't ping, but gives me some decent acceleration. I don't think I'm going to get much else out of tweaking here. As you said, there is a point of diminishing return, when you just don't get any more from further adv...

Are there dangers with excessive advance even w/o knock?

For those following my other issues, I had a hesitation/surge at cruising speeds. Looking at my KAMRF tables, I had values that were up in the 1.12 range for low loads/low RPM. I modified the MAF table to account for this and now my surging appears to be gone. It drove beautifully once I got that so...

Reluctantly, I ran the MAF tune in EA with a 30min datalog including a few WOTs, interstate cruising at 80mph, stop-n-go, and 55-60mph cruising. Then applied the adjusted MAF values from EA. I didn't want to do this yet since I was afraid I'd just be "tuning around" a problem. On the drive home, I d...

On a V8 Ranger conversion, that's easier said than done. Getting to the back vaccum hoses is not easy. They are slammed against the back firewall with little to no room to see anything. You kinda just have to feel your way around back there to disconnect and reconnect lines. The two X-factors in my ...

The best I can figure is a vaccum leak as well. I just assumed that the O2s would clue me into that one but they appear to be bouncing beautifully around .48v. But regardless, a vaccum leak is very possible. I haven't taken the upper manifold off and checked everything, but that was my next move. I ...

Now you are thinking like a programmer. The limitation is in the EEC has predefined memory sizes for each parameter. When a PC that we use to tune uses a true 32 bit value and tries to conver it to a 8 bit or 16 bit you will obviously loose resolution. I wish there was a better way to explain it bu...

Ahh, so what I need to do is: 1. Enter in all the kg/hr values into CalEdit that represent my MAF 2. Click away from the MAF page so CalEdit will skew them to the next closest value that'll fit in the ECM 3. Once I know the skewed values, EA can give me voltage values that corroborate with the skewe...

When I 1st got my TwEECer, the 1st thing I did was read the ECM, then save that tune. Looking back at that tune, those two parameters you are referring to are set to MAX=200°F and MIN=100°F. I'll adjust that down to something more reasonable. How low should I go with that lower parameter? 20°F?

You are right, I don't know what I was thinkin'. High voltage is rich isn't it? I guess that's actually good news for me.

I'll give that a try and see if that gets rid of my problem. To the best of my knowledge, I didn't have the "Update ONLY" checkbox selected, but if it is one of those things that can select itself, that may be the problem.

I'll tinker further and report back what piece worked.
