Thank you Brian.

 

Sign me up! This is going to be a great year to own a 951! I think this could be a year in which the 3L+ cost could be reduced significantly! Tuning is going to reach new levels and will be available at a very reasonable price! Thanks Joshua and Sid for your contributions to the community!

 

I'm gone for a weekend and you announce it?

Just couldn't wait, could ya!

PS - I'm home now... just... FYI...

 

Hell's to the yeah! .25 volts more powah, biotch!

But seriously, this is what I've been hoping to happen with this product since it's release. I think it's time to start saving those pennies up...

Josh, you have a PM inbound.

 

Thanks for the complements! I agree - this is a great time to have a 951, and is only going to get better

Ha - nope, I think this is really cool and wanted to share it...

Got the PM. Ha, though .25volts might not sound like much - it allows us to quantify changes, and that is the real benefit!

 

kick *** josh. I'll be happy to spend some more money with you

 

Is the relationship of MAF voltage to horsepower a linear one? Looking forward to this.

 

+1

 

Not linear, much more of an exponential. I will probably do the conversion so the logger shows flow in both terms of voltage and lbs/min - so we can directly deduce HP.

 

You mention that it will log WBo2 that is fed to the DME. Does that mean the M-tune can handle a WBo2 signal instead of the o2 sensor?

 

The M-Tune still uses the NBO2 signal for its closed-loop operation.
The WBO2 signal is in-addition to the NBO2 signal, and does require feeding the WBO2 0-5volt output to the DME. (usually one wire)

 

I see. What are the benefits of feeding the WBo2 to the DME if the closed loop is run off the NBo2?

 

The immediate benefit is logging WBO2 along side everything else (rpm, boot pressure, injector-time, ect). Then you can make direct AFR adjustments based off of the logged data!

 

Great.
It's been a while since I did any work on my logger. I had planned to log most of the things you mention, as well as external stuff such as transmission temp, fuel pressure, brake pressure temp and oil cooler temp, oil pressure. Steering input and brake pressure would be fun to log as well. Will it be possible to connect hook sensors up to your logger? Will it be possible to connect a smart phone to your logger via bluetooth to show the data in real time on the phone? I mean in the future...

 

That is a lot of stuff to log... Perhaps I will look at doing a multiplexer in the future. But for the moment, what it can log is the stuff I've mentioned already. (I do believe I have found a way to log knock as well - I will be testing in a few days)
