Nistune Formal Release 1.2.21 [update]

[Matt]

If you use an R32 ECU (or when I get Z32 working) then that ECU too... I dont support the R33 ECUs

[diehard]

Are we able to upgrade the firmware from the nistune software or would we have to send the daughter board back to get the new firmware put on?

[Matt]

You cannot reflash the board in the ECU itself via the consult port, so the boards would require removal and external reflash from ourselves or someone with a base image programmer

I am starting to get numerous requests about the flex fuel/launch control updates due to postings on various forums

They are close but still not in final stages yet. I have been doing some testing and need to make further updates due to issues with fueling. This will take time so please follow this thread for further updates when available. Thanks!

what about issues with ve maptracing for n15 and others? Its really annoying and confusing that we cannot use ve table when needed... There are several topics open regarding this,it looks that tps scaling failed to calculate when max tps is under 500mV...

[Matt]

It is still on my list to look into next. I've been hounded about launch control and flex fuel for ages now so am doing this at the moment so I can knock it off my list

VE table investigation was based from my R34 ECU but I will have to look into other models so that will probably take several full days to work out properly

Will flex fuel be locked to the zietronix sensor or will it be usable (with calibration curves like afm) with cheaper sensors such as the GM one?

The zeitronix unit uses a gm sensor, it converts the sensors output to 0 to 5 volts. You can't just uses the sensor on its own due to its output.

[Matt]

Zeitronix just converts the flex fuel output frequency to a voltage (0-4.96 volt) which the ECU can use. The ECU inputs are normally 0-5.12v (9 bit A/D input) so some minor rescaling was required in the ECU code after my initial firmware write

I've got a couple of Arduino minis which I'm going to program up with the same thing as the Zeitronix does. I think we can do the Flex fuel input stuff for about $40 for the Arudino mini with plugs and about $60 or so for the continental flex fuel sensor (which I think are the ones used by Zeitronix, Haltec etc)

[Ben C]

That's fantastic news Matt.

I am getting excited!

Hope your able to fix the trace in the VE table, that would be so awesome!

[Matt]

Yes it will happen. One thing at a time... I'm finding I'm getting diverted from tasks and end up with a lot of half completed code otherwise

I'm gaining a lot of knowledge and increasing my disassembly listing whilst doing the launch and flex updates. This had led to better disassembly around the VE map areas in the ER34 and Z32 (95-96) so when I get to that part it will be easier for me to do anyway

So far S14A flex fuel (and S13) code has been done. I'm running S14 at the moment in my car on various flex/85 mixes. Currently about 90% done with the R32 code base. It does its calculations a bit differently (and Z32 has individual injector calculations so you could trim each one) so there is a bit of discovery going on

[nickbucher]

Is the s15 code as simple as the s13/14 code or does it need to be rewritten?
