Nistune Forums

Sold my Z so won't be needing nistune any longer. z32 ecu with romulator, plms cable and single user license, 680cc injectors (originally from rx7 turbo II , 6 blaster ss msd coils with wires, two ptu, z32 maf and an untouched rb26 engine harness. Asking 500.00 cad.plus shipping. Pm me here or reply...

Has anyone considered third party hardware to convert the maf itself to map and leaving the ecu software alone? There are a number of converters available for this that require some datalogging to tune the converter before removing the maf. An intake senser is a must to do this properly. A temp corr...

I use turbo injectors in my L28ET. No problems with them. They are from the 87 or 88 turbo.

Make sure your erths on the Z32 are the correct way around, if you body earth the sensor ground you get a massive loop and idle etc changes with voltage load... ie turning lights on changes idle... The pin next to the 12v source (12v is far right) is ecu ground, the pin next to the signal (signal i...

I have seen this in the maxima world with the emanage ultimate. Dsm world uses the maftpro with other auto brands that seem to have their own favorite hardware to tune with. I think Eric has done a conversion using the z32 ecu.

I'll get it setup on the weekend. Thanks Matt.

Going to the track on 25th. Need to test a bit before heading out.
But no pressure. Lol

What is your timing during the decell issue? Try adjusting it to see what happens.
Do you have a lightened flywheel?

Hi Russ. Have you tried to change the warmup timing max? This constant is found just below the injector latency change version 0.12.11. I can't remember which way to adjust it but I changed those values when I ran my engine with that ecu.

Type 4 OBD-II and Type 5 prototype boards are now completed so software work will continue again. I've put the above changes into a stable build release tonight

What vehicles are going to be covered with the new boards?

What about the acc_coefx100 ? Is this a constant?

So the "Fuel Increase Rate" constant is the "acc_coefx100"? ROM/Matt, have you tested the tables to see how the injection time reacts? This is my understanding of ROM's descriptions: F900 tells the ecu to decide if the throttle is being opened. Does it decide by how much? F910; i...

I just switched to a blow thru z32 maf and in my case it required a good amount of retuning.

You might want to consider dropping the maf voltage from the lightning maf in order to read more flow or you install it into a larger housing or do both.

I rely heavily on methanol injection for detonation control/octane and found that I lost a few horsepower at a high 10 afr and didn't gain anything by leaning out the afr's beyond 11.8. I tune for 11.2. Timing is critical and holds the key to power more so than afr's. YMMV

First off setup your fuel and timing maps to reflect the scaling you need for more resolution. You can increase fuel by using a larger k value, increasing the pw in the fuel map or by increasing values in the vq table. Take note when changing the timing maps to ensure you have the same timing in you...
