In need of a decent base tune for safcII

[jason91dsm]

Ok so here is the deal I've tried using the rre site for a base tune but they all were either way lean or pig rich. Here is a list of mods done please help me with a good base tune to start with.


4G63T
stage 1 block with 2g pistons 8.5:1 bored .40 over
balance shaft eliminator kit
2g throttle elbow
3" innercooler piping with front mount
20G turbo on 18PSI
tubular exhaust manifold
2 1/2 turbo back exhaust no cat
dsm graveyard 272 cams
2G maf with bottom and side honycombs out and screw flush
550cc rc injectors
in tank walbro 255lph pump


boost gauge and wideband used
SAFCII

AFC should be 0'd out. I'd turn the boost down for a baseline run and make sure your wideband readings are somewhere in the 11.0-11.2:1 range if you are running pump gas. Use a datalogger in conjunction with your wideband to monitor knock. Be careful tho. Those 550's will start running out of room quickly at 18psi on that 20G.

Ok I've tried the zero out thing before and I run off the charts lean. The benefits of having the safc2 is 1 it has a knock gauge and 2 ut has a 30sec logger so I have logged everything and at 20 psi I have no knock at any rpm other then idle and its a phantom knock then

I use to have basically the same setup as you I would ditch the safe and get dsm link lite, the safe isn't really doing anything but tricking your Maf sensor.

The SAFC does not read knock in DSM's. The 30 second logger doesn't log anything useful. You need to do exactly what NOSLO2PTO said.

Also, I just tuned a 2g last night with a 20g. I pretty much ran out of injector on low boost with 750cc injectors. This car had ECMlink V3 on speed density.

Sorry in last post I meant to post
safc not safe.....stupid forum runner

 

[jrohner]

If you have a logger you should be able to get a half decent tune quickly.

Id ditch the Safc as well plenty of better options out there or take the advice thats been givin atleast

 

[jason91dsm]

When i get the money i am getting dsmlink but have to make this do for alittle while. and if the SAFC2 does not measure knock then why is it measuring knock and hooked up to my knock sensor. not being a smart ass or a dick saying you are wrong, just asking a legitamate question.
