I would more than glad to show you everything in person when I visit Texas in a few weeks.

Sounds like a plan! Any idea what day you might be able to stop by?

Toyota likes their tunes like I likes my womens!

11:1 is normal, even on a nonturbo engine. They have to keep the cat from overheating at high rpm. Engines with more expensive components can handle higher heat or can reduce exhaust temperatures. This is a $25,000 car. It's not going to use expensive materials, expensive engine architecture, and expensive control strategies.



target AFR has already been logged with an OBD scantool, see top graph. Nobody's logged open/closed loop yet and posted it--a generic scantool can actually read it if set up properly. You also can look at estimated catalyst temperature with a general scantool. Nobody's posted it yet, but I suspect it's around 950C at the limit. If it gets hotter than that, the catalyst will prematurely age. It's not something an owner would notice but it affects in-use emissions testing from the EPA.

Random just noticed your in Norwalk. I will be there for work in July Carry on!

Interesting that they're running more ignition timing in the torque dip from 3600-4000, and less in 3200 & 4400-4600 to lower the spike.

Is that the stock map or have you already bumped up ignition timing to try to take the dip out?

Also noticed the map changes to 400 rpm break points in the torque dip from 3200-4400.

What he said! I would also like to know if those pics are the stock or a modified map?

If you look at my log data this appears to be the stock map, running load along the 0.70 column, and the torque dip happens right as the map is pulling timing. I live at 5500 feet above sea level which is why my car follows the lower load value ( I figured I would answer because I know somebody would ask). At sea level you would progress further along the load axis and it would pull even more timing.

Hey Guys,
My Name is Ben Dagenais, I work at Lachute Performance and my prior job was Tech support for EcuTeK for 8 years.

The work I am doing at the moment is simple but takes ages. I have to confirm all the different maps present in the ECU (maps needed) so that when you present your car to a tuner... he will know that the parameters available for tuning work and are reliable.

I have not started to tune for power as I don't have the understanding of all systems yet.

I will get you some screen shots later tonight!

Ben

[Ben@lachute]

This is a stock timing map, but there is more than one...

I am working on understanding which one is used and when!

so the stock map is the one pulling timing and potentially CREATING the evil torque valley. So if we adjust the timing out, the valley probably, or mostly, goes away.
