Thread: Calum R/T ECU and Nistune software question

ID1000cc inj, N62/Z32 mafs, 6062 bb turbo, 3 bar fuel pressure. Bottom end is built and head is all Brian Crower w/ a port and polish



My build thread

I've attatched a file to this messaged, download it and give it a try, you probably will still need to adjust the k-value to dial it in.

I already disabled the o2 sensor so once you have the idle at 14.7 by adjusting the kvalue you can adjust the cruise portions of the map.

This is just a DE bin set to n62 maf and 1000cc injectors so you might want to copy the det timing map over an what not..

my guess is this will get you idling / cruising but from there you will probably have to play with the ttpmin/max and possibly the load scales an such, although i did let nistune make some auto adjustments so hopefully it'll get you in the ball park.

Hooray for someone knowing how to use Nistune :]

Thanks. I'll give it a shot on Tuesday, which is the next time I'll see the car probably.

DET timing map only goes to 6800 RPM :[

i've been using nistune for little over 3 years, however i've never used it on a calum.



to your edit, you can adjust all of those rpm numbers, just be sure to have the timing / fuel maps have matching rpm's, same goes for the knock maps an such.. try not to get to wild with the spacing tho, i like to keep around 400rpm increments or so.

just get the car to idle an cruise at 14.7 man an we'll go from there.

Well the car will idle, but only with a k value of like 50,000. I'm not sure it will even start with the bin you made, the k value is only 16,000. I need to pressure test my shiz and make sure I don't have vacuum leaks before I continue.

i hear ya man i had some goofy problems when i first changed injectors an maf but have since ironed it out.

im really liking the nemu because i dont really have to touch the K value any more unless i change the maf, i can just use the actual injector size to adjust wide spectrum fueling instead of tweakin the k value.

No, that's how you figure what value is for that cell (like all non 192 cells)



What ECU are you using, USDM or JDM one? You can't use a U13 bin on a USDM ECU.

There are plenty of different tunes out there, search calum's section on this and old forum.



ECU interpolates. But it's best to tune so that you never roll over, that way your in control of what the tune does.

thats what sucks about 16x16 maps tho, you can only space the rpm's out so much before you lose resolution

I'm using a used OBD1 Calum R/T v1 that I bought used off the forum. It worked really well with my t25, but now I'm having trouble with the new setup lol. That U13 bin I got off the forum, I think it was somewhere in the ROM exchange section. I dunno if it would work or not, but it idled nice with the k value changed.

This was going to be my starting point. How do I know if it will work or not?
