Nistune Forums

today i had a look at the ignition map while online. i wish i could say that i understand it better, but it seems to get more confusing. up till now, i have only been looking at the timing value reported in consult view. first of all, i should mention that i noticed my neutral switch was not on. gav...

nistune menu.jpg mine looks slightly different than this one below (different values at different points on the scale), but essentially the same idea. yeah, it must be a load value. thanks for the direction. mapping guide definitely looks like the place to be. lots to read tonight. but what i guess...

ok, set the timing to match nistune again. more specifically, the consult page of nistune. i did not unplug the tps, and i had to wedge a piece of paper behind the throttle stop to get the rpm to the point where the timing wasn't jumping around. got both the consult and actual timing marks to land s...

Awesome, Ok I’m definitely on the same page now. Next chance I get, I will try a few different rpm positions, and compare the results. I’ve only done a few boosted pulls so far at this timing, and each has been awesome. No knock. One more trip back and forth to work before I can get under the hood a...

yes indeed, plug wire jumper between the coil and the spark plug. when you say that i'm at 11 degrees advance, do you actually mean 11, and that this is too retarded? or are you saying that i'm advanced by 11 degrees too much, meaning 26? maybe i should back up and describe the process i'm using, ju...

well i have a bit of news to report. i had one of those, "i'm and idiot" moments. long story short, while triple checking my ignition timing, i found an ignition coil not fully plugged in. so i've been testing on 5 cylinders so far. and here i thought it felt sluggish because of the timing...

I’ve got the base idle down at 630-650, so definitely not too high. The manual says to set it with the timing light only. Doesn’t say anything about comparing to consult, so people must have been doing it that way long before Nistune came along. There’s also a chance that I missed something like a f...

Are you guys sure about the timing procedure? When I ran through it again the other day, the display on nistune was again stuck at 3. I could adjust up to 15 easily using the light alone. Very clear results. The only spot where the computer and the gun were the same, was when the timing mark was jum...

Update- Switched to the smallest spring (green) and it will hold 6-8 psi up to 6000rpm. Didn’t get to test much, but it seems to creep up to 12 above 6000rpm. Difficult to test on the road though. Going pretty fast, and it is all happening pretty fast. Any hope of tuning this in? I’m thinking it’s t...

Thanks once again. Makes sense.

I also got a really comprehensive response from tial today, confirming that the internal bypassing is normal, and that the spring ratings are not exactly accurate due to variances in exhaust back pressure. I take this to be along the same lines as wastegate priority.

Ok, I won’t worry about the internal leak. But wow, that’s crazy about the spring not really being accurate. I guess I’ll have to try a lighter spring setup.

Thanks!

Today was the road test. Almost all is well... It is over boosting. I have the tial mvs set up for 10psi, but it’s going well beyond. I pressure tested with compressed air, and could hear a leak. Bypassed the manual boost controller to eliminate that. Tightened up all clamps and the banjo bolt on th...

Excellent! Thanks for letting me know. I feel like I’m on the right track. More updates to come. Sound clip too. The sinco manifold is pretty great. Update* the vct wasn’t plugged in right. Had to contort my hands to get a good grip on it, wiggle and push, and it dropped on properly. Fires just fine...

well, i triple checked all my hose clamps, and vac connections. didn't find anything wrong there. plugged in while not running and decided to try the vct test. didn't hear any click. unplugged and metered the connector, and i can watch it switching on and off. plugged it back in, but still didn't he...

well i'm finally at the point where i've been test running the engine. sounds great on 3" straight pipe at the moment. haha. had a bit of an issue chasing a high idle problem. fast idle was 2000, and warm idle was 1500. also has an intermittent misfire. changed out the coils to a set of audi r8...
