If you have the 8-pin expansion connector with yours there is a +5V pin on that.

Mine is only a 4 pin. 14v, sensor and power ground and an11.

That would be nice to have though!

Jesus. I feel retarded I can just use the 5V from the MAF sensor. Idk why I was struggling with this so much.

Its an optional plug inside your case that connects to ANtemp 4. It also has pins for +5v and sensor gnd.

The MAF is battery voltage so +12V

"If you can't find one... make one "

Made a simple voltage regulator today to get 5.0v for my ethanol sensor.

Well my ethanol dilemma has been solved. Many thanks to Simon at Link ECU. 18 hour time difference helps also.

Here is where the mysterious DI#3 was: Simon said D16 or D17. Looking through the manual I found:






D16 is the winning ticket. I'll be looking for a blue wire with yellow stripe. Should stick out like a sore thumb.

He also mentioned that I could ditch DI#5, which is the brake switch. If I had to speculate that is what cancels the cruise, which I'm not using.

I did some soldering last night and got all organized and prepped for installing the knock block. I didn't want to rush since I had to get up at 4 this morning for work, so I can just do it tonight or tomorrow. I sound like a broken record but at this point 1 or two days isn't worth jeopardizing a year of work.

I tore out my motor one year ago the sunday of sno*drift

Welp. All wired. My cutoff time for being in the garage is 9:30. This is fine with me tonight. I will check all wires tomorrow. All I have to do is plug in the 4 connectors into the Link, and hook up my +14V, Wide Band, and Ground to the Expansion plug and I'll be done. Those already have soldered ends on them so it is literally a plug and play operation.

While I hope I NEVER have to do this, I made it so that It is reversible to stock by leaving enough tails there.

I also wired in oil pressure while I was in there.



That is what I ended up with. Anything with a -- is a change. I am in the process of making 100% sure all the tables for the sensor and calibrations is right.

Finally - I had a 35 minute conversation with Miles at Fine Line tonight, VERY Helpful! We shot the **** about his Flex Rex as I just named it, that they finished a few years ago, some other misc stuff. The important stuff that pertains to this thread is the fueling!! He gave me some good pointers to try to get the car going.
So I dont lose them I'm going to write them here.

6ms master
Trim 5%
10-11% at idle in the main fuel table
Store and save ( I always forget!! )
Make Idle in Open loop. That way it goes to the table and not off the sensor.
Watch Enrichment.
Timing should be good since I'm running 8.2 compression pistons.
Store and Save.

I hope to have my car running by tomorrow. It is realistic. It will be 50 Degrees. I should take a vacation day tomorrow.

I will second that! I had a great experience and an awesome deal on a new vipec from miles at fineline.

It has been nice being able to communicate I will say that.

Dyno day has been set.

It is alive!!

It is still oscillating between Rich and Lean though, causing it to raise and drop in RPM. Maybe visa Versa though, maybe it is trying to drop in RPM but I have too much fuel or something.
I need to go through and smooth it out to see if that will help.
Holding the car at a steady 2,000 rpm it will do about 13.5 - 13.8 AFR all day though.

I dropped fuel pressure to 40psi at the rail and 8ms master and 15% trim got it going. I need to bump it up to 9ms master and 2% trim to get it finer tuned.

That good news Layvon! That sounds a bit rich at a steady 2k. It seems like it should be 14.5- 14.7 AFR. Are you trails ring it to PnL? How much time did you book with Junior to do the tune or was it just a start time?

I was talking with Dylan there via email and he said the 2pm slot was open, and knows I'm getting a tune on the link. Yes, trailering down there.

It is a little rich I agree, the limited tuning ability I have is part of the problem. I was trying to get it to idle at 1500 rpm so it could just sit there and be happy.

I ended up dropping trim to 10% so I'm at 8.8ms of injection for a master. Having said that, this is what I just adjusted fuel to. I haven't tried running this yet, because the only cells that would run well are the ones that I have in a 2x2 square.



I just tailored out from 100 kPa and 0 RPM to 2500 rpm and 0 kPa. I have no clue what that will do, but if anything it is a bit rich, which I'm fine with at this point.

Once you have you master set there is no need to ever adjust it again and you shouldn't have to unless you swap injectors. It effects global fueling. If you want to tune AFRs once you're up to temp do it in the main fuel tables. You want your fuel master and trim at a value so the mean fuel table value is about 50. You're gonna have to tune that live with wideband feedback.

You're probably oscillating because you're swinging into cells that aren't tuned yet. Are your AFR's swinging too when rpm does?

That is what I was attempting to do today, but I wasn't very good at it. Tomorrow is a new day though. I feel confident I can get it onto a trailer as is, but driving it around wouldn't be a bad thing either

I played with the autotune a bit and if you set your tolerences right it does a pretty good job mapping fuel quickly. Tune ahead helped a lot too. You need to have your AFR target table set if it isn't already.

AFR table is set, I didn't 100% understand the tolerances on the autotune, but I was also trying to do it on the fly with out research before hand.

when we used the 2.2k resistor, as soon as the car started up the eth % went wacky.
bumped to a 10k resistor and it was good, but would drop out during a pull.

further conversations with Simon brought us to a 12k resistor, but the car has been down and unable to test.

this was on a v10 plug in board.

Interesting, my ethanol is holding at 9% solid. Right now it isn't a parameter for anything it is just there. Ill consider that if it starts getting screwy.

What was your 5v source from? I made my own circuit and threw capacitors on it so that the ripple is minimal.

I pulled 5V from the vipec accessory harness. I also tried the 5V rail that gets sent to some sensors as well. It was back in spetember, i cannot remember which. I just know when i left the car, it was wired to the vipec accessory harness.

10-4. I cannot justify a $70 harness right now even though it would be a cleaner install.

I think I spent 14 on my little circuit. 9 of which was the breadboard

After running pig rich from above, I came up with this. Seems to be a little smoothed out too. It was tough to tell looking at the old 3D map though because it was spread out. I'm out of ambition today to go to test it out to see how she idles.

obviously I dont plan on driving anywhere with this, but Just want to get it idling and able to pull onto a trailer.
