no problem just trying to get maximum efficiency. can you not get detonation with too much fuel? conversly with too much ignition? seeing as this is at the high end of the rpm scale i tought perhap a degree more timing might help.....this is where my thinking was going on both.....might have to do what gtsboy suggests
couple of questions...i'm sitting here going through some logging i did the other night in my car...here is the scenario and i'm wondering what is the best option...being first time road tuning.
on wot i'm running 11.4 afr's in p15 n17 with a knock reading of 18.
my question i'm pondering is ....should i pull fuel or add a degree of timing? timing in this cell is 18degrees @6100rpm
my mods are in my signature
any advice would be great
thanks.
use some CRC or 'start ya bastard' spray to locate the vacumm leak..the idle will change if you hit the leak. spray around the areas where surfaces meet or where gaskets are used....also any vacuum hoses.
82? wow... my sbc is set to 60 for 16psi. the set figure is a ratio 0 being stock and 100 being maximum boost. i have my gain set to 25. 5 is the blitz recommendation for rb26dett.
I'd suggest contacting apexi support and seeing if they can shed any light on it. Otherwise finding someone who can actually check/repair any circuitry that might be wrong with it (not quite so easy)
umm just one thing i had to have on my blitz sbc was a restrictor....if you look at the size of the pipe on the actuators and the size that the boost controller required...then you usually need a restrictor.
they could probably work together if you can work out what affect having the BeeR take control of ignition away from the powerfc, you'd probably have to set the powerfc fuel cut to be higher than the BeeR one....like a two stage cut i suppose.....
mine use to stall a fair bit too..i run a greedy type rs bov and i've tightened it up a fair bit...before that i had some taiwanese bov and i could watch the piston stay open too long which would cause the car to nearly stall..then pickup again. having the spring pressure set correctly and the right size piping feeding your bov seems to be the right combination...also put zip ties or hose clamps over your airline to you bov.
have you set your idle correctly? get the car up to temp stop the car...unplug the tps....start the car...turn the idle screw on the aac valve till you have it idling at 750. turn car off...plug the tps back in.....if it still runs like shit after that it could be your tps.
