Hey I've got a prob and I'm hoping one of you's will know how to fix it.

It doesn't happen all the time but sumtimes when my car is still kinda cold it won't boost, it started doin it after I changed the oil so I was thinking it might have sumthing to do with that?

Any help would be great.

I'll have a look and see if There's any loose tubes today.

I warm the car up for like 15mins before I drive it, thought that'll be enough?

Btw, if it's not boosting, if I turn the car off and then back on itwill start to boost again. Its weird man lol

Thanks for ur help, galois u calling me a retard? Be sure to say it to my face at the next meet up.

lol, I think you are taking the term "retard" out of context...

Rich - More fuel is thrown into the engine to lower the air to fuel ratio

Retard - Ignition timing is changed so that fuel ignition happens later

What does this mean? I'm no mechanic but my understanding is that the ECU thinks the engine may be experiencing something that may cause damage to the engine and is actively trying to protect it.

Hahahahaha that's hilarious, when I saw the preview in my email I'm like "wtf did I say to this guy?!". Not laughing at you mate, I've read the term "rich and retard" so many times and never once like that hahaha.

No need to get aggressive on the forums though mate, it's all just good fun. If you stick round long enough you'll probably get a lot more shit than that for doing absolutely nothing, some people just love the excuse of being anonymous to abuse people.

I'll elaborate a bit more, but I'm FAR from an expert.

The r33's seem to hit rich and retard, where the engine goes into safety mode, easily when the engine has some extra boost added. The boost level seems to change depending on the car (and weather etc, cold dense air often triggers it), and no idea why but most of the posts I've read have it happening on r33's.

Maybe have a search for rich and retard or low boost or something? It comes up fairly regularly on sau. That's assuming it's an ecu cut issue.

Take it easy though, don't thrash it till you've got it figured out or something might go pop.

Yea I thought u were taking the piss outa me lol

But yea there's afew keyboard heroes out there :|

Well like I said I might take it to uni group when I get chance, it's due for a retune anyways... Last place I took it too f**ked it and it pings here and there on high boost :/

Till than tho I'll be running it on low boost.

Btw it only does that boost cut thing when it's a really cold morning so it might be as u said. But yea it's only done it twice on me in the past month so i dunno.

Honestly thanks for ur info, I'll search the forums for abit regarding rich and retard after work.

Cold mornings mean the motor will be running quite rich untill it is properly warm, It would be miss firing because it cant burn the all the fuel.

How long since you have changed the plugs, they are probably starting to foul up.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My idle is set at 950rpm though - Moving the timing around 20 degrees is not really what I'd call a calm idle. That said... neither is chop, by definition. The LS ECU likes to adjust timing to hold idle as opposed to air. It'd work, but generally speaking there'd be a discrepancy in the base idle and the IACV would want to move the timing around anyway to maintain said idle. I think I'm just going to keep the timing steady anyway. Preserve my engine mounts.  My aircon is now officially regassed. As the guy was reversing I noticed my reverse lights do not operate, along with my reverse cam. This is a bit distressing, because 100% of guides talk about which wire to connect to backup cams as "the goes with the [other color] wire". Often when doing conversions. Unfortunately the R34 colour wires aren't documented Unfortunately I had a T56 Magnum gearbox with it's reverse switch, which also isn't documented. Unfortunately there's definitely not documentation for people with both of these in the one car. Unfortunately I forgot. After many hours of this, I have a reverse cam and reverse lights again. The wire going through the trans tunnel to the reverse switch had broken. Upon inspection, it looks like this one wire had about 7 spade terminals and extensions in it.. for reasons I cannot possibly comprehend. I also spent the 750 hours required to clean up the wiring behind my head unit which now looks like this: This is a monumental improvement relative to what used to be there WRT triple gauges, head unit, traction control, wideband controller, and whatever the f**k OEM stuff still exists there in various states of connectivity/needed. Next step is to check in at the Exhaust shop to see/confirm how much clearance I have, to decide what mid mufflers or 'resonators' (which are just straight through, narrower mufflers) I can add and hopefully cut out a lot of exhaust leaks, pinhole, v-band or otherwise. But first step will be to 'take a look' before the next step.

      It's most likely the bolt/bush where the cover bolts back wore and allowed cover to move forward.

      Still haven't put the injectors and R35 AFM in so we can tune the bloody thing for the HG highflow it got mid last year! I think I can forecast the upgrade path to a bigger twin scroll, external gate, Haltech, flex setup, Samsonas, dis dat, etc will be .... a while away!

      Should have taken that opportunity to slot in a twin scroll turbo setup. Maybe next time.
