Thread: Calum R/T ECU and Nistune software question

Yes, that's because TunerCode has it's own firmware .

Awesome. Thanks buddy I will give it a shot in a few mins

Still being difficult to start. Been cranking for like 5 or 10 min with it not doing anything. Wish I had Nistune, bet its a lot better than this Tunerpro garbage.

If I change the k value to 55000 and change injector latency to 2.5 ms, it will fire on one or two cylinders and die. But that's it...I almost wanna just take it somewhere and let them fool with it and tune it on a dyno.

If I change to the old bin I made, the car will start. So I did that and let it warm up, switched to your bin, and it won't do anything.

I think you need to read up a lot more before you should pass any judgements still. Read this page a few times: ECU Tuning

Injector latency at 2.5ms??? That seems like a lot, granted I've never dealt with your sized injectors but even my 520cc STI's are at .68ms latency.

I think you're right, Vadim. I'm just guessing, trial and error kind of thing.

I did finally get it to start with lynch's 2nd bin. Latency at 1.5ms and k value at 40k. Started to give it more fuel under a load and decided to stop and wait since I don't have a BOV. It wanted to spool lol. Still need to work on getting it to start cold. I don't know what the deal is with it being cold. I have to make it dump fuel for it to do anything, and if you touch the throttle it dies. Warm is a different story though. It will rev and is driveable.

Edit: So I read most of that write up, and most of it went way over my head. Helped me understand what some of the values mean and how they are interpreted, but it doesn't really help me adjust them properly. I think I am going to ditch the Calum ECU. The more I think about it, the more I think the Nismotronic NEMU would be a lot easier for a beginner like me. Where most of the values are simplified for dummies like me attempting to tune their potential 400+hp monsters. I feel like the Calum is going to get me nowhere really fast since there isn't any good software for it and I don't exactly have access to Nistune. If I sold the Calum, I could get about $350, then add $200 and I can buy a really nice ECU that will later offer MAP support. Why wouldn't I upgrade while the NEMU is reasonably priced?
