MAFT Pro & SAFC, or DSMLINK?

[TurboBlue]

Well, first and foremost, I'm curious as to which method of tuning would work out better for me. I have access to a Dyno as well as enough knowledge to tune. Not at all calling myself a "tuner", but i understand the basics. Right now I am just running a 1g MAF, 650's ( i know they are a little big), EIIIB16G, re-wired 255 and AFPR. I'm tuning with just an SAFC and venting atmosphere. Got 3 consistent pulls at 13.5 psi with sparatic 0-3 counts of knock and timing 22-24*. While attempting to up the boost, im seeing 20-43 counts of knock starting as low as 3000 under WOT. Any help would be greatly appreciated.

I'm looking to increase the controll of my tuning, and wasnt exactly sure which would be better. I'm assuming DSMLINK, only because you can controll timing and other things MAFT PRO cant. But honestly, i dont know the ups and down of the two setups.

SOrry for the ramble, just hoping someone can help me solve my knock issue as well as giving me opinions on which to run. Thanks

I wouldnt run any engine management that doesnt give me full control of timing.

Exactly the timing control is important expecially in our 1g's with the aggresive timing map. Plus all the features of dsmlink is incredible. $600 plus an eprom which can be found at junk yards or bought for under $100 if you have a good source. Ebay is crazy on eprom prices.

Well i actually already have a socketed EPROM with a DSM stage 3 chip in it. I just cant run over 13.5psi of boost without the engine knocking something crazy. I know i cant just add timing to compensate for the knock, so i guess i have to figure out just why its knocking first.

It might have something to do with the dyno. I'm using 4 DynaPacks, so it might just be vibration setting of the knock sensor. I dunno, im really kind of stumped.

Thank you for the input, any other advice would be greatly appreciated, thanks.

Adding timing will give you more knock. Pull some timing out and they may help you out.

The clear choice is DSMlink, especially if you already have a socketed EPROM ECU. There is nothing further to debate. Get DSMlink, and sell everything else you don't end up using to help offset the cost.

It sounds like your base timing is off.

 

[TurboBlue]

So you think timing is the issue? Right now its set at 5*BTDC, at least with a light. MMCd Datalogger tells me something like 10 or 11, but even turning the CAS all the way back only brings it to 8* with the logger, which should i go by, and should i try running like 2-3* base instead?

 

[unclesam099]

Your logger is showing what the computer "thinks" the timing is or what it wants to believe it is, not the ACTUAL value. You have to ground the timing pin and set the timing by rotating the CAS while using an inductive timing light.

 

[TurboBlue]

thats exactly what i was going by, and that sais 5* BTDC, think i should back it off to 2-3* base?

WOt timing is controlled by the Pro with a keydiver chip. The Pro (and the Gen2) has FAR more adjustment than an SAFC does out of the box that would be a waste.
