Can you borrow some sort of external wideband? LM-1, etc? If so, use it and corroborate what you're seeing. Rule out the O2 sensor first. -Jorge

Hey guys, thanks for the kind words! Actually did a tech article on your cars. http://www.pandlmotorsports.com/wordpress/?p=44 <-- Something to check out. I'm starting to really like the MZR! -Jorge

So, here's just a quick, little update. I talked at length with my engineers, and this is really the skinny of it. Can we make a bar to tie the two points together, where you guys are trying to? Sure! Will it actually HELP, in the way you guys are hoping? No. Not really. There will still...

I am by far no engine builder, or thermodynamic expert. But typically combustion pressure should be centralized by the plug. Not off to one end of a pentroof design. -Jorge

Something like that is going to imply some sort erratic combustion burn, almost as if there is some sort of pre-ignition or combustion inefficiency. Its direct injection, so its not like you're spraying fuel along the back of an intake valve and back burning. So unless the incomplete stroke...

Check out Nite's google search, and look at the google article that comes up on MSF. "Rod Bending observations". This is what others have been documenting over there since November. Pretty interesting read. As for detonation being the cause. Every car is going to be different. But...

Nope. The more I read into it, the running theory is that it may be a bad batch of forgings (one aspect), crank loading and crank walk on the other end of it. If these are push style clutches, then it would make sense with what people are talking about (in some of the threads I've been...

:lol: Guess I should have tried to click on my own link. -Jorge

Jeff: Out of curiosity are you on a stock clutch? http://**************************/forum/f10/rod-bending-observations-42105/ <-- Nliiitend1's google search pulled up this. Page one is one of the most telling things, as its a similar thing Magnus found with the crank walk in the second gen...

I appreciate it, thanks! -Jorge

Wow! How it didn't outright snap is a testimony to the softness of the metalurgy! Jeff: The bearings on that cylinder and that piston and rod, if you wouldn't mind, I have a full on light table and camera setup used for macro work. I'd love to do some super high resolution shots of that...

Thanks Trance, I appreciate the heads up and straight forward reply! Jeff, it was good talking to you this morning. If you can post up pictures of the rod. You also mentioned comparing it to a normal NA engine's rod, in terms of how thin and flimsy it is. I'd love to see it compared to your...

http://www.mazdas247.com/forum/showpost.php?p=5100187&postcount=11 <-- Just as an example of how I identify problems. If you look back in Early January of this OP's thread, you can see the dynoplot and the linearity of it. Note his comments about how things are load related. Mazda's MS...

I know you're being quite serious, but I'm honestly trying to understand how this is the worst post ever? I'm being acknowledging, and open about it; where most would hide and try and back pedal. I'm offering and encouraging an open discussion about the technicalities of WHAT happened, and...

Well, that's good to know! I had heard that the rod was the Achilles heel of the MS3/6. Now I know that its much more obvious then I had feared! When you guys get more details on post mortum, please let us all know! -Jorge

FWIW... if the primary WGDC table is setup right, you won't spike. More often then not, its improper tuning of boost dynamics, R/T, and DBW that will always pose spikes. Where all three combined you can make the car do ANYTHING you want. You "technically" can tune out a spike or creep on a...

A few dozen at this point. Nothing too crazy, but consistent results and progress!

Thanks for the kind words everyone! I'm really enjoying using the requested torque model! Makes for an interesting FWD car, when you can really tailor each gears power curve, to the intended use, tires, etc. -Jorge

... and what map are you running?

Well, that's something you guys can simply do in flash (read: AP). -Jorge
