Yes it is an expensive sensor, but it is still less then buying a controller and the sensor, like most other brands require. The Bosch LSM-11 was originally designed for industrial high temperature gas furnaces, it is very durable. It's not even close to being the most expensive wideband...

There's a few more Aarons on this board too :biglaugh:

It sounds like you hit fuel cut, and it's good that you did! That's the whole purpose of fuel cut, to save your engine in an overboost situation. Doward is a good guy to ask about the topic of turbo selection. I couldn't explain the benefits of an aftermarket twin setup over a properly...

It's more about picking a turbo that is right for the engine it will be installed on, and the intended use of that engine. There are many factors involved. The compressor map for the turbo can tell you a lot about how it will perform on your engine. A big turbo will spool at a higher rpm...

lol, it's the devil talking through me right now!

We know you like the dark meat Charles, I was talking about sharks though. :biglaugh:

I wonder which race of people they would rather eat?

Was that a specific value that Motec recommended, or did you experiment with a few values? I figured that having the least load on the tach output of the ecu, while still maintaining stability on the meter, would be the best way to go. I used a pot and went from about 1k all the way to 10k...

Yes, that circuit will make the tach read correctly. Thanks for posting your video! So just to get this straight......it's a 1g engine, with a 7m ignitor, and a few 1j parts for good measure?!? Man, I love the way you work! :icon_bigg That is very cool. The 7m ignitor is a great unit...

I hear you guys on all those points, and I didn't want to come off as unsympathetic. I guess when you get into the big horsepower you gotta pay to play though. If you can't spend the money on the clutch, one possible option is to not make so much horsepower that a upgraded single plate clutch...

The 3200lb pressure plate might be too much for the master, but more importantly it is very hard on the thrust washer in the engine. I don't know why people keep buying those. If you really need that much clamping force, look into a multi-plate clutch.

I am well endowed.... JK, it's for my big belly. :biglaugh:

More cool stuff today! I got my oil pump back today! I dropped it off about 3 weeks ago to be blueprinted and moly coated. I had mentioned that I wanted to make a 7m oil pump flow better a few months back to the machinist, and the machinist mentioned that he had long been considering making a...

pm sent!

It was making positive boost at 2k rpm on the freeway, and 10psi by about 3k rpm. I have the .81 AR Precision housing.

GT4082 with the Precision exhaust housing is working very well for me.

Tell them you don't like butt secks, maybe they'll let you off. :dunno:

If you don't have a wideband, tuning it yourself will be difficult. It's best to either get a wideband or take it to a dyno that has one.

Almost everything you can imagine is covered in the help files. From the help section called "injector scale" included with the software: Injector Scale The injector scale is used to set the resolution of each increment in the main fuel map. Injector Scale sets the max fuel available ...
