I will try and explain this as thoroughly as possible cause it is a little hard if you haven't experienced the problem yourselves. I had an apexi AFC installed and tuned about a year ago. From the dyno tune, the power which was produced was 250 hp (roughly 160 kw). That was with a boost control, intercooler, greddy bov, turbo back exhaust installed. Bearing in mind, it was boost was only adjusted at 8psi.

Now, recently I have had a problem driving on freeways at approximately 100km when the car starts to kind of stop start. It feels like the something is pulling it back and only last a couple of seconds and then will happen again at the same speed. I previously had a service and the guy who serviced my car adjusted the fuel cut defender on the apexi and that seemed to be ok but over 100km, it still gives me the pits. I rang up a dyno tune guy (another one, not the one that tuned my car) and told them and they said that the apexi afc is not really compatible with the skyline r33 95 model's standard computer and suggested I remove the apexi and boost control to make it more efficient. Now that doesn't seem right considering many posts on this forum tend to express how great the afc is. I don't want to bring it back to the original guy because it is too far and I really don't have time but I am not too sure what the other one is talking about either so does anyone have any ideas?

the safc is compatible with the 1995 model ecu. i suggest you chat to another tuner

going by the advice given...

I'd be changing my choice of tuner as if they are saying its not compatible...

They do not know what they are talking about

    • And also there were for sale scams and the like. For sale posts need piccies, and not having piccies makes it harder to do a driveby scam.
    • And I forgot to add my *** footnote to the above post, which was that the pipework mods would be even more significant than what had to be done for the highflow. So just add that onto the list. Pipework mods are no killer, just made the tasklist longer at a time when extra tasks were not welcome.
    • I mean he could post them to imgur or the like and create a link. But yeah, spam bots absolutely will post pictures in their first posts.
    • Ah ok, reason I asked was for the sake of not having to upgrade everything if the turbo couldn't be capped.
    • pffft! My alignments are starting to take 3-4 weeks each. Bugger overnight - that would be a dream! Overnight is when I leave it on stands with the rear suspension in pieces, hoping I can remember where I was at when I come back to it. I have to set the car up on a level surface so I can get decent camber measurements, then try to set the RUCAs to the right length to get that right. Then I have to put the car somewhere else where I have enough room to set up the bumpsteer gauge (laser, paper, mirror), so I can dial out that. Then I need to go measure camber again because changing the tension arm length affects that also. Then I need to measure toe, and I can't do that to my own satisfaction at home, so I have to put it on an actual aligner. Then I have to go back and fix the camber again, and if that took more than a half a turn, decide if I want to set up the bumpsteer measurements again. I previously had the bumpsteer almost completely banished and then I started changing things again! And that's only the rear end. Not even gotten to talking about the front yet. And this has been going on in the context of me discovering a seized bolt in the LHR FUCA bush at the upright, hence needing total disassembly to replace that bush and the others that were not far away from the same outcome, replacing sphericals in the front end and making a mistake that resulted in needing to do it again, which is only half done right now. It's a selfmade nightmare. Only have self to blame, etc etc. But regardless, I am so complelely unable to utilise the services of a normal wheel aligner that I have no choice. I haven't found a shop in my city that does "race" alignments - and by that I don't mean I want my car to be set up for racing, but the set of adjustments that I have available and that need to be used to do the alignment are the same as you'd find on a race car. I haven't looked everywhere, but there doesn't appear to be the equivalent of the motorsport focused shops that are present in Sydney and Melbourne. And such an alignment would cost $300, and you only want to do it once in a while, and you don't want to find out that you have to replace bushes and bearings and such while you are spending that $300 so you have to come back and spend it again a week later. So I stay living in my self made nightmare for the moment.
