> What would happen if I set them to 500?

Why would you want to do that ? (unless you want to destroy the engine due to massive flooding and borewash)

Yes, looks ok now, but it seems you were still driving like a grandpa ? To be certain is to leave the "grandpa mode" and do a couple of full throttle runs. If it bogs and stutters all over the place (usually as soon as boost comes in), I would have another look at the air-intake and look f...

Looks like there is a problem with your MAF.

it seems to randomly spike in voltage, causing TP to spike with it.

Maybe a wet air intake ?

your current (type 3) board will not fit the 1991 TT ECU, which will be a type 2

I have seen that turbotimer feature with a Z32 (type 2) ECU. It is one of the options/features of a twinchip for the Z32 (http://twinchip.ch/) Not sure how it is done. On a sidenote, I once had a defective Z32 ECU that kept the engine running, even with the ignition turned off and the key out of the...

Not trying to discourage you, but by trying to create Nistune software for the 350Z you will probably open a can of worms and get yourself a LOT of extra work/problems. there are many revisions and different ECU's for the 350Z (uprev already covers most of these.) see: https://docs.google.com/spread...

If this is on a Z32, then most likely this is caused by the IACV (idle air control valve)... it's feed from the LH intake and can cause imbalanced AFR's at idle/low throttle conditions. if you watch AFR vs. IACV opening percentage, you may be able to see if this is the cause of the imbalanced AFR's ...

A better way would have been to show the max. cfm/airflow a certain airflowmeter can measure accurately. But this is not known for all AFM's a Z32 AFM can measure up to 850 CFM...above that it will just put out a voltage of 5.12v it'll depend on many factors of how much power an engine can make with...

Check your PM

the driver has been removed from Windows Update, and an updated driver will be released next week. A PC won’t be able to communicate with a counterfeit FTDI chip with the new driver, but at least it won’t soft-brick the chip anymore.

>good on FTDI for finding a way to kill the counterfeits, but bad for all end customers like myself who ended up with those parts yes, a bit harsh they are targeting end users that may not know they have a device that is using a counterfeit FTDI chip. Lots of reports now of bricked keyboards, mice, ...

Just heard of reports that diagnostic cables (or RS232-serial converters with FTDI chipset) that are using non genuine (fake) FTDI chipsets, will be bricked by the latest FTDI driver update for windows. Chances are that many cheap ebay Consult cables that use a (non genuine) FTDI chipset, will stop ...

Does it work when you put the old eprom back in the socket instead of the Nistune board ?

(Also I presume you did try the ECU on the car before the Nistune install and it worked ?)

I once got this working on an Arduino using a 74HC14 (schmitt trigger) and frequency counter library or freqmeasure library...can't remember which one I used, but I think both worked.

vga is for video

this is what you need if your computer doesn't have a serial-port:
