Hi guys. I'd like to hear input on the following ------I recently installed a mines tuned non programmable ecu, it got rid of r&r holding ign at about 17* tru the revs at wot on the apexi multichecker. The prob is it pings off boost at low rpm in higher gears showin up to 50* on the multichecker. I retarded the timin via the cas to see if this would make a difference but..... it did'nt Dont matter how much i retard it still shows 15* on idle and it made the car lazy going to about the same readin as before AN IT STILL PINGS!!!!!!

Should'nt adjusting the cas affect the timing somehow?

Also i tried to richen it up in that area with an safc2 -it retarded it by one or two degrees but IT STILL PINGS!!!!!

Any suggestions?

Oh.....with the stock ecu max ign at the same load is about 40* an goes to 8* when it hits r&r at wot RB25det s1 10psi

If this "multichecker" is simply pulling a timing figure from the ecu then it won't show any difference due to moving the cas. The ecu assumes 15deg base timing is set and everything is relative to that. As for why it's pinging off boost at low rpm in high gears... I'd be taking it to a pro quicksmart!

you are using 2 bandaid solutions and 1 monitor only device

throw all of your devices in the bin and buy a real ecu

failing that, if you insist on keeping it, get rid of the mines ecu and use stock ecu

then get the safc tuned properly.

    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
    • I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.
    • If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
