Very interested

Any chance of including the Techedge 2.0 stream? It's documented here http://wbo2.com/sw/logtech.htm

It wont read the techedge stream as it needs to request data first. I didnt need to request anything for the MTS stream (you just sit at the end of the device chain and read data off) so it cannot transmit.

I think it does transmit it by default? b7 - Frame generation 1= Auto is bold so I expect it always transmit data?


Set logging control byte to xx (hex) where xx bits are defined (default = bold) :
b7 - Frame generation, 1 = Auto (always produced), 0 = Manual.
b6 - Frame type, 1 = Binary, 0 = hex/ASCII.
b5 - USR inputs, 1 = scale to 1.5 format (scaled x8 = 13 bits), 0 = raw.
b4 - Frame mode, 1 = debug mode (ASCII/Hex), (See * note below)
0 = normal (binary).
b3-0 Frame type (See * note below)
0 : V1.5 compatible mode.
1 : V2.0 log mode.
2 : V2.0 calibrate mode.

Out of interest what will you be doing with the data from the flex sensor? It's going to the logger is that right?

Yeah the logger gets the data using an I2C interface and inserts it in to the XDL like the normal aux data (aux data size just grew) so it can be played back in TunerPro. As the device can also be on the bus an 11P or 12P ECU could in theory request the ethanol content and then adjust accordingly, but it would need code done in the ECU for this (its on the list for 11P, but 12Ps lack of RAM will likely mean this is not possible).

I think it does transmit it by default?

I think your right, was looking at the logging section and the small picture showing commands going to the Techedge. It also has a repeat rate so even more likely to be a stream that can just be read. Can use a terminal program and see if it does spit data out automatically.

Yeah, I'll test that. Still keen for the board, how would i program it? via serial?

I thought I saw a reply early this morning but might have gotten lost in the topic split.

With the serial stream, perhaps a innovate and techedge stream switchable with a jumper? I have both so they're both interesting but prefer the Techedge WB... sorry for the feature creep

Keen to give the board a go if you get a chance to build/mod them. Perhaps new topic?

[VL400]

Yeah there was a post, but it got lost in to a black hole with the topic split!

Will look at adding both but I dont have any techedge gear to test/develop with so it could be difficult.

I have eprom programming, hot air soldering and happy to test where ith my gear if you like. I expect the firmware is on a SMD chip for size?

[VL400]

Luckily much easier than that, uses a small utility to make firmware changes over USB.

cool, ready when you are

just a quick aside, i've been looking at the northstar setup again as a 1uz and a340 has come into my life. with the northstar setup being tricky to fabricate, apparently it'll run quite happily with only one crank angle sensor if the cam position is working. probably takes longer cranking wise to find where it is though. have you heard of anyone having a go at this?

[VL400]

Never tried that, but its possible that it could still work with one failed crank sensor and use the cam sensor for sync - its a likely failure mode so wouldnt totally surprise me. But then in saying that, the Commodore V6 18x/3x trigger that also has a cam sensor connected to the ignition module wont run when missing one of the crank triggers.

Keep us updated on what you find out. If you come up empty on it I do have a solution with my ign module, and you can keep the dizzies, leads etc making it look factory still.
