Ok,

Lets not start any bitch fight here, I am just wanting to get an idea of a tuner to goto.

I have got no time to muck around with my car before the Drag wars to get it sorted, therfore I need to get the S-AFC done on a dyno.

I was wondering about the best place to take the car for a tuner who can set the adjustments quickly and correctly and hence saves me some $. Needs to accept credit card payment too.

It looks like people will finally get to see how much power my car doesn't make to achieve a 13.4.:)

INASNT,

That's right I don't 'need' a dyno to tune my car but, I do need alot of time and I don't have any before the trip and then very little time when I get back.

Besides, from the sounds of things Steve knows his stuff and He'll probably get more than I ever would have.

Steve,

I was going to get some ngk 7's since I expect the rev range has lifted since the cam gear etc has gone in. My old rule of thumb was 6's for 6000rpm 7's for 7000rpm 8's for 8k and so on. Does this sound like a plan mate?

I think people are expecting to see you have 250+hp dave, to justify your runs. What they dont realise is the mods, like the lightweght flywheel, wont show an HP gain. Dave might only pull 220hp with 10psi, yet his car has run quick times, just another reason why you cant use a dyno to gauge how fast a car is. Remember aswell, dave's had a fair wack of experience in racing cars, so he probably drives a lot better than most of us.

You know I just had another play with the S-afc and I thought 'yay - I've got it all sorted' cause I had a whole day without fuss and ping and a little bit more timing.

Then when I least expect it..... ping and knock. I have the tune sailing too close to the wind I guess but, boy does it go now!

I have added a little fuel in the correction map up top +3. I have kept a fair bit of timing to boot. I am tempted to go a colder plug and see if I can keep the advance but if what steve says about the 6ES is right then there is probably another way around it.

I have my trusty Autolite racing plugs that are a range cooler (7 equivalents) these I had with a gap of 1.1mm before the other bits went in and although a tad cold for the rich stock ecu maps they ran a little better than the 6ES up top all the same (then fouled doh! I expected that). I'll have to clean them up again. Anyone else tried the Autolites?

Steve,

Do you reckon there is more power to be had if I retard the timing (its about 5degrees past the last mark at idle) and then do a leaner correction using the 6ES plugs?

Also if you would like me too I can bring the car in sometime on the 14th of march.

      Sag as in the windows start to slowly open themselves, or they're just slow to go up/down with engine off?

      It looks like it needs a big worm gear drive on it to control the rotating, not a few sloppy pins!

      As Duncan said, first there was OBD, which few cars used, then came OBD2.   Now an interesting point, OBD2 isn't even for what you want to do. OBD2 is for emissions testing. There is some sensor data on OBD2, but it's up to the manufacturer what they're putting on it. Most scan tools operate on UDS, which like OBD2 is a standard built on-top of CAN. UDS specifies how to structure a message, what very limited things mean such as "read memory address" but it does not specify what is stored in which memory address, that is all up to the manufacturer. You either a scan tool compatible with that vehicle, or to know how to reverse engineer all the data, which can take a VERY long time and a lot of vehicles to get it right. Oh and then the manufacturer does a firmware update and changes what's where... Ask me how I know that as fact Oh, and by the time you've got the scan tool that supports all the manufacturers stuff, well, you're back at "But a consult cable and the Nissan software" The main difference being most manufacturers software these days works with the same hardware readers, as the readers are built to support J2534 which is another standard for how the PC communicates with the tool to make it do specific things on the car...

      Rotisserie is fully assembled apart from centre connector which obviously isn't required until the car is on it. It packs away fairly neatly and doesn't take up too much room. (Now that I actually have some room after my clean up!) Overall very happy with the quality of it.  Assembly was a piece of piss.  The only thing I didn't like was that the pins that lock the rotation lock wheels in place were a bit of a dick in a bucket scenario. It allowed the arms to rotate a significant amount even when locked in place.  To fix that i measured up the hole and went and grabbed a couple of 18mm fully threaded bolts and a thread tap to suit. I ran the tap through top and bottom so it was threaded both ends.  Then just threaded the bolt through both sides.  It has made a massive difference which hopefully you can tell in the before and after video how much difference it made. 20250207_161431.mp4   20250207_161431.mp4 Hopefully back working on the car over the next few weeks.   20250207_162801.mp4

      R34 Gtt Wheel Offset Advice

      By GTSBoy · Posted

      I think my main complaint with your idea is that there is a veneer of idealism spread across it. You want the simple numbers to make it easier, but all they will do is make it easier for someone to come to the wrong conclusion because the fine details will kick them in the nuts. As it is right now, the tiny bit of arithmetic is NOT the obstacle to understanding what will fit and what will not fit. The reality of trying it is what determines whether it will fit. If you had a "standard rule" that R34 GTT guards have that magic 100mm space from the hub face to whichever side you were worried about, and someone said "excellent, this wheel is only 98mm in that direction, I'll just go spend $4k on them and jam them on my sick ride".....they would just as likely find out that the "standard rule" is not true because the rear subframe is offset to one side by a fairly typical (but variable) 8mm on their car and they only have 92mm on one side and 108 on the other.
