Thanks!

Your going to be on the road in no time

Looks GREAT Vee Dub Nut!!

Loving the nice neat install! Please please keep us posted with lots and lots of pics of your install!

Cant wait for the next update!

Again, a great "pictorial", your EDIS drawing stating missing tooth location is the best I have seen AND I agree.

My "haste" comes for MY world wherein the "common" question "Which tooth is TDC on the FORD engine EEC-V OEM ? ".

I too am enjoying the continued reports, now another observation :

1. The pictured fuel pressure regulator shows NO manifold pressure reference, am I correct ?

If this IS the case, then the BARO fuel correction may need to be INVERTED. (NPC vs PPC)

I would be WORTHY to discuss the section of the MS calibration "object" that does this work.

Oh, ok.. By the way, I stole that picture from the MegaManual

Correct, there is no manifold pressure reference.

Tell me more. This is all new to me, and I'm still learning. I know that several people have used this regulator with MS without issue, but I'm not aware if there was any specific modifications done to the MS or code to do so.

The modern EMS will have a 100% dedicated Barometric pressure sensor. (BARO)
This method IS REQUIRED to provide real time information concerning changes in altitude (air pressure) to the EMS
The other required "load" sensor could be MAP, TPS, MAF, etc.

The "Redline" EMS has this feature (MAP & BARO TWO separate sensors board mounted).
This feature states that I may have correct information provided by my observations AND our users.

Now for a succinct description :

1.The BARO correction with the fuel regulator "ported" to open air pressure will need an INCREASE (add fuel) in fuel correction when the engine is "throttled" to maintain constant AFR.
2.The BARO correction with the fuel regulator "ported" to manifold will need a DECREASE (remove fuel) in the fuel correction when the engine is "throttled" to maintain constant AFR.

Now, I am not a MS user/expert, someone else needs to share that area of the GUI (object) that can be adjusted in your case.

The simple fix is a regulator that's properly referenced, but you could always do the MAPdaddy mod so you'll have 100% realtime BARO correction. DIY Autotune sells a kit, I think. In my experience, it's not a real big deal unless you climb mountains all day long. Even going over the Grapevine in CA I didn't notice the difference, it just runs a little richer is all. You can do a running restart if need be at altitude to recalibrate the ECU, MS takes a BARO reading in the first few cycles when it's switched on. Just push in the clutch, kill the engine, then restart it.

My Point, missed by "miniman", is that the MS has NO code to support the position of the fuel regulator air pressure reference location.

The statement, if correct about "MAPdaddy", would make the BARO correction in the opposite direction.

Lance, when I can understand what you're typing I'll attempt to answer what you post.

What i don't understand is the constant thread jacking to push the redline product, and put down everyone elses way of doing things.

I wasn't gonna go there, since I do my fair share of pushing MS/MJ stuff around here (though I don't make a dime off it). I just wish I could understand him(?).

My concern is to help all those here with information including "Vee Dub Nut" AND those who produce the MS code.

When I see an EFI problem, I will try to correct, solve, or repair the issue.

The point of "BARO" correction with respect to the fuel regulator "air reference location" is often overlooked.
This is even stated by remarks made by "miniman".

THAT is my point AND if incorporated into MS code those users would have a better running engine.

Now, lets work together and FIX the problem that is stated by "miniman".

Lance

I think some reading comprehension is what's needed here Lance, because you've misunderstood me again. What I said was if you reference the regulator correctly and put the mapdaddy on, you'll never have to worry about altitude because MS will correct for that. But like I said, it's not that big a deal. If you're very worried about it, you can always restart the engine and it'll run just fine at altitude.

Man.. just been beat the last few nights after work, and didn't get much done on the car. After a few good nights sleep to catch back up, the wifey and I covered the ECM mount. My wifey is very handy with the sewing machine and fabrics, so I enlisted her help to get the mount covered.

As it started:



I broke it all down on the table



Started cutting out my vinyl



Couple a folds here and a couple there, blam blam with the staple gun and whalah.



I put some velcro on the bottom of the upright supports so it would bite into the carpet and stay put. Here it is in the car



And some of my wiring notes I made when I was flying to alabama last week



I'll be using the terminal blocks to distribute out some power between a few different things, as well as provide a central location for all of my engine grounds.

Anyways.. hope to make some good strides in getting the wiring in order this weekend.

That looks lovely! Very nice neat job there!!

I have to admit though that that wiring diagram looks SCARY! Is it really as scary as it looks? Or is it actually kinda straight forward? Sounds like you might be playing with more than just the MS wiring.

Awesome stuff dude!
