Build Thread The Hoopty Chronicles - New House, New garage, New Car?

I also looked at your cam choice you linked on the other thread. I like that profile(I'm only a semi-newb at profiles). I did want to ask you though...why not a custom? Darn near the same price. Actually it is the same price as a non-billet core custom. I think it will run great as is but was just wondering. I'm not trying to be an elitist and say the custom is the only way to go...just that there may have been a better choice for the price point.

last i heard he got it for free so.....:shrug:

I thought really hard about going custom. But I don't plan on having this motor too long and don't have huge goals for it. This cam is a proven performer and like previously mentioned, it was free.

I'm just putting this here because every time I've used it nothing catastrophic has happened.


Please be aware that this marks the official switch to the new mushroom cloud (used to ward of mechanical evil) and appears as:

Thank You. :)

Megasquirt is in and running. Some settings were off making it hard to start but we got there. Will get a video up shortly
Yea you. And to think,.......you built the thing that is now controlling fuel, and spark from a kit. And now you'll be able to change everything just by plugging in a laptop......all it takes is a willingness to fumble your way around in the dark so you can find the light switch.

Yeah, I completely fubar'd it yesterday. But I think my light switch is @a91what - he's been graciously lending a hand via email. I am going to re-do my tune right now and see where that gets me. He pointed out several issues I had, so we will see where that gets us. I owe him a phone call at some point today, but I have a drywall project at a buddy's house to go mess with :notnice:

Somehow, I was thinking that same thing. He has offered to help when it comes time for me to consider re- starting the thing.

I don't have much to update since getting it running, but for those of you watching this to see how it goes, the people that get their car driving 'within minutes' must have a few genes that I was born without or they had another guy with a similar setup send them a base tune. Here's how it went.

I got the car started on my own Saturday morning using a slightly modified base tune from the DIY website, but it ran really poorly. I knew it was a timing issue and eventually found the setting to tell the MS that the base timing was 10° where it was set at 4°. Switched it, turned the key and it purred like a kitten. Sweet!

Decide to rev it and it pops, spits, and bucks. Play with the fuel and timing, and it hates it even more. It'll rev to 1500 and wont really go any higher. Played with it most of the day and got nowhere, really. It is important to note that I was *NOT* using the upgraded software that has VE Analyze live which costs $59.99. (I'll expand more on that later).

That evening, I messaged a91what to see if he would mind sharing his tune with me to see how his tables were set up. In short, not only did he share his tune, but he took the time to explain the entire TunerStudio program to me over the phone and spent his sunday evening emailing me tunes back and forth. That's very cool in my book!

We still were not able to get it to where it would do more than idle well before I called it quits Sunday evening. Eventually, I convinced my wife to let me upgrade to the VE Analyze live (autotune) I haven't been able to mess with anything since, but I have another plan - I'm going to keep my AFR and VE tables where they are and use the timing table from the tune a91what sent. From there, I'll use the autotune function and see where that gets me. I feel like that way, I'll only need to mess with the timing table with the computer controlling the other table. I hope that gets me somewhere.

@a91what - I think my biggest question with the timing is at idle. With the stock computer, if you put a timing light on the balancer, it'll read 10-14° (typically). There shouldn't really be any advance at that point, right? Once the RPMs increase, then the computer starts to advance timing as I understand it. I guess my question is, what is the 'true' timing at idle if it's not 10-14°?
 
It's been awhile since I looked, ( since my car isn't running now) but There is a way to set the timing so that what the ecu thinks, and what a light tells you are in sync. It's one of the first parts of the "before you go further" in the mega manual. I can't remember where it is, but it's in there, I had to adjust mine as well, especially since I'm running EDIS-6. There was a ten degree differential between the two, until I set that.

But,

My tune does the same with regard to running poorly after I jab the throttle. I just assumed that that was because I'm only tuned in the idle area ( since I had no existing table to start from),..but maybe there's still something not addressed in the initial settings.

I based mine off of these tables. When you pull the spout on an A9L the timing will revert to base. With the spout in the ecu can vary timing to help achieve target idle, this is more effective than the iac. I saw 20* timing idle with my stock A9L.
That said with the MS it like closer to 16*, I have changed my timing bins to reflect a lower timing 10-12* in the 75-100 kpa bins so startup is much smoother.

Ah, I understand now. I spent a little time Sunday looking that table over but never put it side by side with what I had to see how close they were. But I assume the table you sent me is pretty close to this.
 
Also, what you have the trigger offset set to is the lowest point that timing can be retarded to.
So if in the trigger wizard you set the offset to 10* (you must have the distributor set to a mechanical 10* advance or nothing lines up) that is the lowest timing you will achieve. What is in the table you build is the total base timing. When data logging you can set the graphs to show base timing, and actual commanded timing so you can see any discrepancies.
