Im booked into get my car tuned next thursday, since the pwr fc was tuned last, i added a gtx3076, cams, 550nismos, 4inch intake, bigger dump, and Z32

It was booked in to be tuned a week ago and timing and basic stuff checked and although was running rough but drivable, just. i ended up missing the dyno cause it took longer than expected to get it ready.

ok so the problem is silly me started playing with the computer, i hit yes to initialize and now everything has reset to stock.

So i either copy someone elses fuel and ignition map and try to limp there or just tow it , rather not tow it so can anyone scan a few maps so i can try , cause at moment it starts and is showing engine light.

as long as its not leaning out and runs on light throttle that will save $$ on towing it.

i have it set on VG30 and had the injection correction between .7 and 1.2 and it is just shaking, as soon as i touch the throttle to reverse it just stalls or wants to , no power, it has no ms data, so ill try the .18ms

is that what your pwr fc has? what about the maps and ignition they all just say 100 across all boxes, should this come up accross like 100 100 105 110 115 etc? just want some numbers for low revs and idle

Your in the wrong menu.

Initialize it again to undo everything you've done. Select VG30. Go into the Injector menu (not Ign/Inj) and set the first column to 66.5% and the second to .18. You shouldn't need to touch the main maps for simply limping it there. Also make sure the boost control kit is turned off if your not using it, from memory it's on by deault.

hmm ok then ill try that and see if it wants to run,

what about the check engine light? its on all the time, maybe it will go out when i select 66.5% and .18

What can i do to ensure its not running too lean, i take it those stock maps will be making it safe along with the above adjustments?

when you INIT the powerfc you need to do the self idle adjust, if you dont it will instantly stall when you tap the throttle

my advice

read the PFC FAQ (in my sig) about DATA INIT

1. perform DATA INIT

2. dont start the car

3. set AFM

4. set injectors

5. turn off boost kit

6. start the car

7. let it idle for 30 minutes as per self idle adjust

8. baby car to tuners and away you go

if you skip the self idle adjust you get a car that stalls instantrly in most cases

if you dont turn off the boost kit and you arent using the boost kit the check engine light stays on because it cant find the map sensor. the boost kit is on by deault when you DATA INIT the PFC

thanks for that info, i tried it out just tonight 66.5% and 0.18ms and its not working, i have no idea whats doing here, it ran smooth for a short while and sounded sweet under a rev but then started breaking down like a wrx sound, shitload of fuel came out the tail pipe, i noticed as i locked up car.

what about accel inj time, does that need changed? i can see 1000rpm 2.4ms 0.6ms

2000rpm 3.4ms 1.1ms

i think i might have to just tow it on a trailer, it was starting to make like a light knock noise as it was wanting to stall, cant be good

Shouldn't need to change anything other than what's been mentioned already. What do the plugs look like? All this fiddling could have fouled them up pretty badly. It sounds like you might be best off getting it towed, if you do just make sure you take a spare set of plugs with you incase the current ones are no good.

I'm curious why everything has been addressed except for the cams, you can't run bigger cams on a basemap and expect it to idle.

Personally I would put the stock afm and injectors back in, modify basemap and confirm its running (with the cams), add the 550cc injectors, modify basemap again, then finally the z32 afm and finish off the basemap

well there just poncams, most people say they wont affect idle at all, it was running ok before the cams , its more the z32 that made it run worse, constantly stalling , i think its time to put it on a trailer, i dont wanna stuff it up anymore.. :unsure:

Going to put some NGK platnium plugs in today and new throttle gasket and regasket the blow off valve just incase. Was going to put on cam gear but might wait and see what happens, anything over 280kw will be good.

this. assuming you have a rb25 the injector settings will be 66.5% and +.18ms and the afm is VG30

Dropped the car at the tuner today, you were spot on, the problem was wet plugs, must of been from the first few attempts starting it,

he ran it lean to clean them up and it came good, then i drove it to get fuel, already feels great even without the tune, just waiting for the dyno now :)

    • Have you not seen geospy.ai? It can now give GPS co ords to within a metre from a photo, even if it's a random photo you take inside. Supposedly at the moment only the government/law enforcement has access to that... Supposedly...
    • I've got the rear ones, they're certainly beefy. I need to take them to my driveshaft guru to check over, he's very fussy about the quality of components so I'll let you know if they are made of cheese by a blind man.   Are you in Australia? A mate just had a set of EN26 shafts made for his K20 Lotus by our fabricator which were quite cheap (compared to Driveshaft Shop) so if you can procure the CV's and draw what you need he'd make them for ~$800 for the pair.
    • Had I known the diff between R32 and R33 suspension I would have R33 suspension. That ship has sailed so I'm doing my best to replicate a drop spindle without spending $4k on a Billet one.
    • OEM suspension starts to bind as soon as the car gets away from stock height. I locked in the caster and camber before cutting off the kingpin. I then let the upright down in a natural (unbound) state before re-attaching it. Now it moves freely in bump and droop relative to the new ride height. My plan is to add GKTech arms before the car is finished so I can dial camber and caster further. It will be fine. This isn't rocket science. Caster looks good, camber is good, upper arm doesn't cause crazy gain and it is now closer to the stock angle and bump steer checks out. Send it.
    • Pay careful attention to the kinematics of that upper arm. The bloody things don't work properly even on a normal stock height R32. Nissan really screwed the pooch on that one. The fixes have included changing the hole locations on the bracket to change the angle of the inner pivot (which was fairly successful but usually makes it impossible to install or remove the arm without unbolting the bracket from the tower, which sucks) and various swivelling upper arm designs. ALL the swivelling upper arm designs that look like a capital I (with serifs) suck. All of them. Some of them are in fact terribly unsafe. Even the best one of them (the old UAS design) shat itself in short order on my car. The only upper arm that works as advertised and is pretty safe is the GKTech one. But it is high maintenance on a street car. I'm guessing that a 600HP car as (stupidly, IMO) low as you are going is not going to be a regular driver. So the maintenance issues on suspension parts are probably not going to be a problem. But you really must make sure that however your fairly drastically modded suspension ends up, that the upper arms swing through an arc that wants to keep the inner and outer bolts parallel. If the outer end travels through an arc that makes that end's bolt want to skew away from parallel with the inner bolt, you will build up enormous binding and compressing forces in the bushes, chew them out and hate life. The suspension compliance can actually be dominated by the bush binding, not the spring rate! It may be the case that even something like the GKTech arm won't work if your suspension kinematics become too weird, courtesy of all the cut and shut going on. Although you at least say there's no binding now, so maybe you're OK. Seeing as you're in the build phase, you could consider using R33/4 type upper arms (either that actual arm, OEM or aftermarket) or any similar wishbone designed to suit your available space, so alleviate the silliness of the R32 design. Then you can locate your inner pivots to provide the correct kinematics (camber gain on compression, etc).
