Perhaps the first actual working Variable vane turbo setups on FreeEMS.

I would "suspect" it has to with the point of the ADV, being for pre turbo applications. I've seen one in a oem car. Also I believe the design tolerates higher temps than the 4.9 and 4.2 does. It would surprise me in order to meet the goals it was setup for that was one of the penalties i...

oh goodness, chrome, I have used that horrid of a program before.

well if you do have a working analog input to use my recommendation goes to the AFR500v2 unit.

It's shocking how much more error the ADV has over the 4.9 and 4.2 https://dl.dropboxusercontent.com/u/56698189/all3Bosch.png I would "suspect" it has to with the point of the ADV, being for pre turbo applications. I've seen one in a oem car. Also I believe the design tolerates higher tem...

5)Has a known pressure compenstation curve from ECM Yeah. But it's about 4% per PSI of exhaust back-pressure. At just 4psi, that's +/- 16% !!! So, without an exhaust pressure sensor and compensation mechanism, it is not very accurate at all :( Unless you have next to ZERO back-pressure. That's the ...

+1 for ECM AFM1000 units http://www.ecm-co.com/img/products/a1000_lrg.jpg likes 1)wide range of lambda readings I have the A unit and it reads from .55 to 1.24 lambda, AFR stoich point is 14.56 They also have other units that read down to .3 lambda and units to read leaner 2)Long harness with barrel...

Figured I posted these two to for the current talk on dwell and cranking

why don't you fix the input to read 5v's it seems like this is a known issue in the honda world and they have a way around that input and to fix it.
or perhaps move it to a different input and make sure the tuning software can let you do that.

What NTK sensors have you dealt with? I have seen the L1H1/L2H2 and the newer LHA sensors. Of those, the LHA seem to have better response times. I'm pretty sure that the different grades of sensors are just hand-picked samples of the regular production parts that have been tested/calibrated. Just c...
