Nistune Forums

I actually did try a 0.1uF cap from the line to ground and it shunted the whole signal. We tried two different laptops. I'm thinking a new serial converter is in order.

Tried a few different resistors down to 100k and nothing helped. I'm thinking of trying a different serial adapter. It's so weird that we can go out logging as long as I hold my thumb against the backside of the pins, then within a few seconds of letting go the serial data freezes...

confirmed that as long as I hold my clammy thumb on the pins of the connector the serial data is happy... weird.

Gonna try soldering a 2Mohm resistor from TX to ground, and if not build an RC filter on that pin.

OK update! We are able to log but the serial data is becoming corrupted and giving a frame error in nistune. I have included the raw serial data where I saw the weird ascii character fly by. I'm assuming this is what is tripping nistune up. We have tried grounding the ground pin on the serial connec...

Hey,

I'm helping a friend get his RB25DET set up for tuning. He has a UEGO and we've wired up the serial connection and have gotten the AFR to read in the wideband box in nistune.

The wideband doesn't show up as a source though in the nistune datalog.

Am I missing something?

Thx!

Thanks Matt.

How does this look?

So I've been having a lot of success tuning my GTI-R and now I've upped the boost to 20psi. I'm experiencing misfires at this higher boost level and even gapping the plugs down to 24 thou hasn't resolved the issue. I'm running fairly rich 10.8:1 with a lot of methanol injection since the fuel here i...

Just an fyi for anyone who may find this in the future - the discussion continues here: https://www.hpacademy.com/forum/general ... any-timing

Hows this look?

Awesome thank you! that makes a lot of sense. I'm used to the tables having fixed axis's's's in my DSM. I'll scale down the low load areas and lower the timing a bit in those cells.

Hey! I'm new here but have been tuning my DSM for the past decade. I recently just built a GTiR for autox. I built the motor with 10:1 JE pistons which makes it pretty snappy but with the 92 octane fuel I'm concerned that the timing table is pretty aggressive. With the GTiR I have a second knock sen...
