With rev limit 8000rpm... does it use the column N19 or only N18?

Also see my base map please... this is with recalc base...

N19-P20

N20-P20

It isn't logical to be so low right? It must be more than N18-P20 right?

Why I ask all theese..

My car run 2bar-30psi and I don't have datalogit right now to tune anything in my car...

As I run this boost I only intersting for row p20 and cells from n13 to n20.

I run the car with rev limit 7500... it was ok 10.8afr! I run it 8000rpm... again ok 10.8!

But ofcourse at theese rpms with so fast car it is different to see the gauge and understand. Also the last rpms before the limit you cannot understand if the numbers are from rev limit or the afr from last rpms.

So I want to tell me if the map seems to be ok to theese cells or in theory the car will be very lean if it will read the N19-P20,N20-P20!

Remember in the foto is recalc the base.

My guess that theese cells must be 40 and 42 is right?

Also the car take out oils at theese boost.. I undestand it because I don't have oil catch can and the oils goes at the turbo and many smokes suddenly filling all the car haha!

The first time my heart stop for some seconds to work!!!

i really need to see both fuel maps: feel free to email me the map [email protected] i will have a look over it and do a few adjustments if neccessary. Generally speaking if the map ponts in the main map are linear accross the rpm points then yes the N19 and N20 points you have highlighted should also be linear (increasing) not decreasing.

URAS so you mean that N19 and N20 must be sure more than N18 right? So more than 39... and now is only 25!!

With 8000rpm limit will be lean the last rpms??

In the foto I have recalc the base!!

You have two emails :)

just emailed the maps back, i had to make some big changes so you will need to reload them via datalogit and check AFR's the original fuel and base maps were full of big holes.

      S1 rb25/s14 starting problem

      When you crank your car, and hit it with a timing light, can you see a steady crank timing?

      Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov

      yeah I was shocked when I checked my spare OEM on and as below that's how they come from Nissan. (side interesting note new NEO gearbox and replacement park lack the brass bush on the tips and its just all alloy) unsure about damage to the box currently back at 1110 to be pulled down/inspected and selector fork replaced as he built it previously and given the never before seen failure on his billet forks he is replacing it under warranty. He said he has used always OEM the keyway tab without issue for years so it could be an unlucky coincidence. I did talk to him about the sharp corners and stress concentration too. Re: hard shifts i got 7+ years out of the OEM one and the fork itself failed not the keyway. so could be bad luck as I said or an age thing + heat cycles in box and during fabrication of billet?
