good point...but should the ecu still inject when there's 0 throttle?

any thoughts on the A/C? i see the AC switch signal on nistune when i flip it on but i don't see a jump in idle so it will just stall out.

stock maxima MAF

So the set up is Turbo -> BOV -> MAF -> throttle body the BOV dumps to the atmosphere so under heavy load the air rushes past the MAF again and dumps out of the BOV. When that happens the car runs a little rich and back fires. is there any way to "fix" that? Basically to lean it out on dec...

Did you change the vehicle ECU at some point? You have a manual ECU installed in an auto vehicle it sounds like J30_VG30_87E00_MT is what you need to use for that particular ECU but really should be using a 87E10 AT ECU We dont have that image. Manual one should be fine the main difference is the f...

car specs: 91 Maxima (J30) VG30E motor Nistune version 0.10.12 So the Nistune board in my ECU is listed as 87E00. The image files listed that i see as being closest are: J30_VG30_1991_BaseMaxima J30_VG30_87E00_MT The car is an auto transmission...does the MT mean it's for manual transmission? Does i...

So it's been a while since i updated the software. Everything was working fine before the upgrade. I did the upgrade and when i click the consult button to connect i get the Extended Consult error. Version 0.10.12 Build Date Sep 8 I'm on the same laptop and everything. nothing has changed except for...

maybe do something half arse to get people in the "know" and once people can understand what needs to be done someone else can make a decent video.

so weather got cooler and nistune is reading 25 degrees C and the car will not start. when it's warmer out the car fires right up.

any way to set it so cold start acts like warm start...at least until i get all the issues worked out?

this is a VG30E on a Type1 board.
Thanks!

finally got it to idle right.... so it turns out there was a little leak in the exhaust manifold a little before the WB so that cause the super lean situation or the lean display from the LC1. got that all fixed up and got the car running around 15ish and it idles perfectly fine. the problem is when...

Im not sure the 3-4 inches is enough. I think for Z32 maf it could cause problems, but i cant say for your maf. Perhaps someone else can help u with this... As long as the timing gun shows the same number as consult, base ignition timing is OK :) Oh and just put like 0.5bar (7-8psi) in it and you s...

i think it's pegged at 32...it doesn't go any more over than that. i'll try the recalibrate again.

KillerB has pretty much nailed it but I'd just like to add that usually you'll find that engines will idle nicely anywhere from around 12:1 to about 16:1. This varies from engine to engine but that's a representitive range. Richer than 12:1 and they'll start to get fluffy, you'll smell the richness...

LC1 is not too far after the turbo in the down pipe. OK thats a good place, no chance of sucking in fresh air at the tailpipe. yeah i tried to get as close as possible to the turbo (in the DP) w/o too close and over heating the WBO2 should the MAF be the inlet side of the turbo or should it be befo...

Before starting to tune, make sure the following things are ok: - ignition base timing - Camshaft timing - No air leaks in intake system - Fuelpressure Then start out with a base map for your engine, perhaps with modified injectors or AFM (use nistune for this, and you might want to adjust injector...

So i read the entire nistune manual and i'm looking through the tuning guide but still i can't get it to run right. car specs... J30 Nissan Maxima VG30ET motor 370CC injectors stock MAF with out touching anything the Wideband LC-1 is showing 32. from the manual i'm reading it should be around 14ish....
