Drove it around the block today, smooth as silk.

Gotta take off the 4psi boost cut, but damn it's nice!

new clutch actually engages where it's supossed....had me worried for a second, since im used to it engaging on the floor.

more tuning tomorrow, done for the day.

 

Glad to hear it. It's a pretty good feeling when you build the MS and then drive your car knowing you built the ECU controlling everything.

 

i did about 2/100th of the build, but 100% of the cursing. Just took some head scratching to get spark to work, and then it was just the little things.

Big props the Brian (NeoGen) and Lars (Sheuind) for making my dreams come true..:gay:

Lars, here how the board ended up:

 

Way to go Scot now i gotta catch up.

 

It looks like you are using the VB921 Mod sending out to your stock ignitor. That is not the diyautune mods for the stock ignitors.

also what is that jumper that I circled doing?

 

The jumper that you circled is for the PWM Idle mod. It says in megamanual to jumper that instead of putting in the R39. I had to look that up myself.

As for not doing the DIY way, we had it that way first. There was no way we could get spark doing it that way. So we switched it to how Brads was done and spark worked right away. I have my MS set up the DIY way and get no spark. I am going to try switching to that way and see if that fixes it.

 

congrats man, glad to hear you got that beast running. whats up with the boost cut at 4psi? is that a setting in the software or the actuator for the wastegate?

 

probably his tunning failsafe. it is actualy a smart move on unproven systems.

 

I actually think his boost cutoff at 4psi was something mechanical he did. I forget exactly what he said but I dont think it has to do with MS.

 

Actually it was a MS thing, something I saw in Al's map so I did it myself so i didn't fudge the bucket.....there's just a boost cut setting, so if you boost above a certain point it's like a nice big rev limiter. Advanced > Over Boost Protection

Akaryrye...you acutally have it how i think it should be...look at DIY's diagram again and they have it slightly different than that....but the way you show it is how I think it should be to put it on the correct resistor...either way, I believe it's only for the LEDs.

 

Talking about rev limiters i kind of want to put it on spark cut only and set it for like 6k just to see how it sounds or how well it works. I'm sure it works good, but I was told it will backfire like a bastard if you just cut spark, is that right? I don't have a cat so that part of it isn't dangerous.

 

my rev limit is spark only, works fine. no backfire or flames though...

overboost cut is great, mine's set at 210kpa, it is crucial to have it when you're doing boost control settings.

 

congrats on getting it running. Looking at your pictures reminds me that I have a ways to go on my assembly. I'm only on step 27...

 

Does doing it how you have it drawn work? If so that means DIY's picture is off by one pin to the right. Which would explain why it never works.

 

Well heck, i was hoping for some kick *** flames and bang bang bang noises on a test run using that.
I just set my overboost values. Thanks for the tip.

 

congrats scott. you beat me to having a running car.

 

except now i gotta tune it....I believe I'm using Al's turbosetup.msq as a base, adjusted the VE table for more fuel and my engine constant....it runs great till about 5psi where it shoot lean....gotta figure that one out, then if I'm in low rpms the AFR will start going more and more lean untill the car starts to shake, then it wakes up and drives normal again....besides that it feels nice....going to go look at my logs now.

 

see between 145 sec and 165 sec for the lean issue at cruise....notice my rpms

and between 240 and 250 sec for lean issue in boost:

 

much better....needs a bit more fuel in boost and a bit less in cruise....

 

Even though it takes a little while to get a good fuel map sorted out it sure is nice having this much control isn't it?
