sounds like youve been watching the fast and the furious lol......Granny shifting in essence is changing gears slowly, as for double clutching improving 1/4 times id say no...if anything it would probably make them slower as it would take longer to change than say flat shifting although this may cause wheel sping depending on the cars power. As for your syncros it is much easier on them if you heel toe (rev match) and or double clutch on high rev downshifts, its probably easier on them for up shifts as well but there will be no time benifit to it...afaik.

At the time mick51 and myself were dragracing my car on a regular basis, he was consistantly 0.7sec quicker than me. We put this down to our different approach to gear changing. He used to bang it through as fast as he could. It being my car I was a little slower and gentler. The plus side of a gentler approach is after 4 years of general use ,track and dragstrip, my gearbox is still in great shape....had a C's short shifter in for last 2 years too.

Double clutching makes no difference in terms of acceleration.

The reason people double clutched was because back in the old days there were no sync rings in the gear boxes.

Today however, every single cars since the 60's has sync rings in their gear boxes so you are silly to double clutch accelerating.

I only double clutch when slowing down (heal and toe) when i want to go around a corner quickly and accelerate out of the apex fast.

Ok i've been granny shifting for the past 2 weeks now for a few reasons which i wont go into cos they are boring...

One thing i can definately say is that its done wonders for my shifting in general. They are now far more crisp and precise, something that i hope will carry over when i gp back to driving normally.

Now when i say granny shift i mean shift early, at 3 grand and staying off boost as much as possible. I've found that by forcing myself to change like this with such low revs has made me rethink when and how i shift. Everything is currently slower but my technique has improved imeasurably.

Everyone try it on your way home today, shift at 3 grand no later, keep boost below 0psi at all times. If your anything like me you'll find yourself reading corners and shifts in a very different manner.

    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
