Hi all, Long story short, I had 2200 CNG injectors running on a 26/30. I went to 2400cc siemens which was a nightmare (my fault for trying to run them on that ECU I think), now I'm back at 1650cc bosch. I have loaded my old 2200cc tune, then changed the injector value to 1650cc. Car will only run if I pump the accelerator, soon as I stop doing that, it stalls. Base fuel pressure is set to 60psi. I have a proper tune booked in for Wednesday, just want to be able to crawl my way down, they are literally 10 mins away rather than get a tow. If anyone can take a look at the attached tune and log file, I would greatly appreciate it. This forum has been a massive help so far and I am in debt to a few smart people on here already. Cheers. 1650_start2.llg 1650_tune.pclr 1650cc_start1.llg

Thanks heaps Adam. What injectors would you recommend going?

Hey guys, 26/30 in a r32 gtr. Idle will just drop off randomly and stall. Like you can set the idle set screw, will idle fine, then clutch in coming to a stop, it will start idling fine the just stall out of nowhere. Siemens 2400cc inj. I think it's had some trigger errors also. Logs and current tune: https://1drv.ms/u/s!AgHRVnwxDzLUj1QHcczZngRSirZ4?e=yFzcY1 So just wanted to get an idea of what trigger is having issues, and what might be causing the idle to just die. Log1 and 2 should show trigger issues, but 3 i moved one of the connectors I was sus on, and it ran fine after that. Going to re-wire that part tonight and it should be good. I'm starting it again with a bit of throttle (only way it will start) which is fine, but I just don't want it stalling at every single light I pull up at. Cheers.

Looks like i need to start with at least switching crank enrichment on and taking a look at that.

Just a follow up to say I used the arcol HS50 2.2's, worked a treat. Just lopped off the connector from the factory dropping resistor, then wired them all into that, used a metal box from jaycar as the enclosure. Just plugs into existing loom now. Ended up doing 896whp, no ill side effects from what the tuner could see.

Have a link g4+ plugin running 2400cc siemens injectors on a rb26/30. Prior to this, was running bosch 2200cc injectors. Cold start was bad with the 2200cc, now its absolutely terrible. Possible the tune needs some work in this area, if anyone can give me some pointers to try and make this any better, that would be great. Cheers.

No problem thanks again Adam.

OK what about: Injector flow @ rated pressure Injector dead time table Short pulse width adder Surely items in here need to change when going to a completely different injector Adam? Cheers. PS thanks for your input/help with this

Hi Adam, I ended up getting some 2.2 resistors, and have it all wired up now with the injectors in. I was just wondering if you might be able to crack open the .pclr file I have uploaded, and make the necessary changes for these injectors? I would be more than happy to pop some cash into a paypal account for you.

Thanks heaps for your help Adam, ill stick to the 2.2 then. I've never heard of these RS guys before, but those prices are pretty decent. Cheers.

Would the bal2 resistors you sell work Adam? They are 1ohm 50w? I'm in Brisbane Australia.

Appreciate that info Adam, know anywhere decent to pickup those 2.2ohm 50w resistors?

Is there anything else that should be noted apart from having to run a ballast Adam? I'm going to be running the standard r32 gtr ballast resistor with them.

OK great thanks Motomattx.

Hey guys, Have recently changed injectors from bosch 2200cc CNG to siemens deka 2400cc. The 2200 CNG's were giving me dramas at high temps using e85. Basically just wanting to know what I need to change in the menu just so I can get it running again and move it out of my garage, and possibly back down to tuners. Tune file attached, any help at all would be awesome. Cheers. 2630.pclr

No worries Adam appreciate it, ill try that first and see what happens.

Log 9-03-20 7;28;51 pm.llgLog 9-03-20 7;27;55 pm.llg Could someone take a gander at these logs and maybe see if something is wrong here? Can't even get it started.

Hey guys, Car is a 1990 gtir with an sr20det. The guy I bought the car from gave us a Link G3 plugin which has since been upgraded to G4 by Link in NZ and had the tune brought across. Pretty sure the guy I got the car from got the ECU from someone else, so it's a total mystery tune. Our current sr20det has 263 cams, 800cc sard injectors and a 2871r turbo, all we are looking to do is get it running reasonably enough to get it down the road to the tuner. At the moment it's coughing and spluttering, and smells very very strong like fuel. Can someone please point me in the right direction of what changes I need to make in PC link just to get it idling and driving down the rd? Help would be very very much appreciated. Injectors are SARD 800cc, no idea what the tune was using before. Current tune attached. Cheers. gtir.pcl These are the injectors is has now: 800cc TOP Low 2 Yellow green Oval 1.10msec 63566

Awesome thanks Adam, will give that a try tonight then.

OK thanks heaps for that Adam. Would simply removing the MAP limit work for me as a test? Your are correct, it drives terrible with light throttle load, its hard to explain, but its very on/off/jerky with light throttle.

OK did multiple trigger scope's few at idle, few at 4K, few at 5k ish. Can you take a look when you get a chance Adam and tell me what you think? Cheers mate.

It has priority set to trigger 1 which is crank, but I don't think the top trigger 2 on the cam is setup at all?

OK ill try that tonight. Did the log reveal that it is having trigger issues Adam?

I can do it again, but pretty sure I did it once before and didn't find any issues.

Hey Adam, Just an update on this, I have re-wired all the triggers with shielded all the way back to the ECU connector for both sensors. I took it for a run after this, still the same. I finally got around to taking it for a run tonight and logging the drive, it happened twice whilst driving on this occasion, one should be towards the back of the log. My tuner couldn't find the issue, so I'm at a cross road. Here is the log: https://1drv.ms/f/s!AgHRVnwxDzLUiWcpUzL-Kv8n6k7_ Cheers. I should add as well, it seems to be most apparent going into 3rd gear, then putting the power down. Also it doesn't seem to be that apparent on the dyno, as in the tuner reported he was getting trigger errors higher in the rev range, but we could do full power runs without much issue. Soon as it hits the street, its pretty much not drive able, soon as it hits 3rd and the power comes on it does it. 20219.pclr

OK cool, yeh I was taking some of it with a grain of salt, the main one I was concerned with was the shielding part. What I have done is met up with the existing nissan CAS shielded wiring/loom. Because the rb26 has no factory crank pickup but, I think I may have run 3 short un-shielded wires from the crank cherry, to meet up with the factory nissan shielded wiring. All i did was chuck some conduit around it. The cam pickup goes straight into the nissan shielded wiring. Cheers.
