Ok, i am having trouble with my P2k on my S14 with a RB26. It ran prior with a differant engine management, but the identical setup will not work for me when i am using the haltech ecu. Here is a copy of my map

its just got 1000cc injectors, i am trying to run this VE. I have the haltech wideband tied into the ecu wiring harness but there no way to make sure its working properly. This is a map for the e11 that i modified to suit my application. Like i said, on my other standalone ecu the car starts and runs fine.

Hopefully someone can look at my map and decide what i should do

here is a copy of datalog

any help would be appreciated !!

When you convert a map to VE, you need to redo the fuel map from scratch. if you have a look at the VE R32-R33 GTR maps that come with the Haltech software (for platinum pro) you'll see what I mean.

How come you chose VE over milsecond timing?

how much power you aiming for? with 1000cc injectors i assume you going for big power, your target AFR table looks a little lean.

Also your engine cc is set to 3000cc, it should be 2568cc (unless you have oversized pistons)

ahhh ok, the engine is slightly over 2640 it should be saved in map grrr lol i will look at it now, i have a holset hx35.. but its not installed yet, i wanna get car running good before i install it

also i went with VE for ease of tune with closed loop, i know i wont make the most power but it will be consistant and reliable

did you have a look at the map for the R32-R33 Platinum Pro? Also when you say it doesn't start, does it turn over? Does it sound like it wants to start?

i looked at the maps and changed almost everything but i still didnt have any luck, i was told to check the home channel to make sure it was doing that for inj pulse and that was ok. it just cranks and no turn over,, doesnt even sound like it close either

hmm i noticed in my fuel base map, there is not a fuel setting for 0 rpm and on the pro there is a fuel setting, i think my car cranks around 130 rpm ish, so i think i found the problem right there but i cannot change it

have you checked to see if all the sensors are working?

on the 30x30 map try setting the cells around idle to about 40%. also might try changing the load sources to TPS and not MAP, as the rb26 has ITB.

tried changing the value to 40% i am going to go over the timing one last time, and go over all sensors, they look good, but tps might have a problem. its actually a rb25 with rb26 harness, and a q45 tb

About that TPS, had a problem with a customers EVO IX, the Haltech (PS1000) ECU hadnt registered that the TPS was connected, though it was, so it simply kept it from starting! Solution was to disconnect and connect it up again :D

Have you had time yet to check if it gets a spark when you turn the key, or if the sparkplugs got fuel residues showing that they're getting fuel? Also we had a problem with the cold start settings, might be because of the fact that its still snow here, but it was not getting enough fuel to start at these the low temperatures.

Good luck :P

When you turn the key on do the pumps prime? also when it's cranking, does the software display any rpm, that will show you if the CAS is working properly? the same page of the software should also have the TPS signal. Are you using a plug and play harnes?

ok i made some progress, the timing needed to be adjusted slightly, i set it to 0 and locked it and adjusted it that way, once i was done i unlocked it. now with a little throttle it wants to start up but dosent go all the way. i am also confused about if my wideband is being seen, i tied it into the factory side of the harness its the haltech wideband but i dont see any calibration options or anything reading it, i wish i could make it display AFR and not voltage, also i am in NJ (usa) been like 70 degrees whooo!!!!

and yes pumps do prime up, i am getting a rpm displayed of around 150-300ish i am using a patch harness, the tps signal is looking awesome, actually i have a question it says its 100percent for tps but when u push the throttle in it goes down kinda like an opposite

Sounds to me like your TPS wiring is backwards if its reading 100% at closed throttle & going down as you push the pedal...

yeah lol i made the change for that tonight, now i just gotta mess with it again tonight wish me luck, i was told i should of done an ignition lock at 15 degrees and not 0, sucks i am alone and dont have a helper

A mate was having problems with the base map supplied to him with his Haltech when trying to get his RB24 running.. if you want, I can send you the map from my stag. It's an RB25 Neo though but it helped my mate get a base to work with for his RB24 so might help get some of the basic parameters setup for running an RB.

Forget about the wideband until you actually get the engienrunning - O2 is ignored until constant throttle (cruise) conditions).

RBs like LOTS of ignition timing to start - in the order of 40 degrees.

i hate to spam my own thread, but when i did a wot and closed read voltage on the TB, it gets the proper voltage, but the reading still says 100% throttle. i configured it from the main, inputs and TPS, if it helps i am using a q45 tb, i was able to make it come up as 0 throttle by setting the voltage on both 100% 0% the same. now it looks like the fuel inj are working, but plugs look very bad, i am going to change them in morning and go frm there. so now my issues remains, car wont start, car always thinks its at WOT unless i unplug tps or adjust voltage, but it reads a voltage when i goto WOT or CLOSE throttle. but i can verify that the car is set for 15 degrees of timing when i did the timing lock on 15 which i was told is btdc. anything else i should check ?

What wideband you got? The one i got from haltech (innovative from memory) needs to be configured in the setup (Press f4), and you can set the AF vs voltage table, and the instrudtions said you need to be very particular with the wiring. But the car should start without the wideband.

Sounds like your TPS is on the wrong way, i think from memory you can change the 0% and 100% voltage values. ie the base map might be wrong, not the wiring. Having said that, i swapped a E11 out for a PFC on the weekend, and needed to change the TPS wiring to get the PFC to work, so the Haltech might need the wiring chaged from the factory settings.

Factory base timing is 15deg for RB20-25 from mem, and 20deg for RB26

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
