MAFT, TMO, SAFC2 Overkill??

[OneFastEclipse]

I am moving into a new setup for my car (57 trim turbo, larger injectors, etc.) and am going to need to increase my tunning options. Currently, I have a SAFC2 and a pocket logger. I am running 550cc injectors but plan to upgrade to around 720's. I feel the SAFC will limit what I can do with such large injectors so I was looking to add something to help it out. I like that fact that the TMO chip allows injector compensation at the ECU but since my car is auto, the other features like stutterbox will be useless to me. I am seriously considering the MAFT but does it allow as good of compensation for the injectors as the eprom? I was thinking getting my based tune with the MAFT and then fine tune and race gas settings with the SAFC. Does this sound like a good plan or is the only true way to get the good idle is with the ECU compensation? Thanks.

regardless, if you have an auto or not, you'd still want the stage 3 chip if you decide to get it cause it'll compensate for the dead time on the injectors which without it, could cause knock like i had. if you get it, i believe you'll wanna set base and aux knobs on the maft to the injector size you have, 0 out the other knobs and then just tune with the afc.

you could always go dsmlink, but if not, it sounds good to me.

So I need the Stage 3 chip along with the MAFT? Since the chip would be compensating anyway, should I just forget about the MAFT and go with my SAFC? Or will that added angle really help me when it comes time to tunning? I remember a site that supplied the chip and the 95 ECU but I can't remember which one it was. Any Idea?

well, what are your goals? if you plan to vent the bov to atmosphere, i'd get the gm maf and maft. it also gets rid of the more restrive stock mas (although on a 2g, it's really not all that bad like a 1g's). you'll want the chip with the bigger injectors. the maft is optional. i believe it's tmo that use to do the chip AND the ecu. think now it's just ordering the chip and finding someone to solder it for ya. but www.dsmchips.com is whatcha wanna look at.

Ok here are a few things you overlooked possibly. You can't compensate for anything over 660's with either the SAFC or MAFT and using both you still can't really compensate for anything over 660's. You can but you end up running so much timing advance you will get some heavy knock for sure. You don't have a 95 so you don't have a EPROM ECU so you will have to find one of those. I've never seen any chips from TMO for the 2G and since TMO doesn't really even exist anymore I wouldn't count them as an option. Keydriver does however make chips for the 2G and you can even see knock with your boost gauge which is pretty nice for a 2G.

I would go with DSMLink or AEM. AEM might only cost slightly more.

DSMLink $600
3"MAF $75
MAFT $200
EPROM ECU $250-300

Your up to $1100+ for DSMLink and the MAFT. You can find the AEM used with sensors for $1200-1400. Would be a pretty steep learning curve for tuning but you can just get it tuned professionally or read their forums and do some street tuning.

i just mentioned this stuff above. also, may wanna look at this....

Whoever said TMO needs to get updated, they're not even around. A place that sells 2g EPROMs & DSMLink is http://www.ffwdconnection.com/electronix.shtml

I understand that above 660's and I am going to need more than a SAFC or MAFT to compensate. That's why I mentioned the Chipped ECU. Won't the ecu with the fuel injector compensation allow for me to tune the car with the SAFC or MAFT? DSMLink is kind of out of my price range. 600 for the program, 250 for the ecu, another 200 for the laptop puts me around 1050 bucks. Not really looking to spend that. Where as I already have the SAFC 2 and if adding a eprom ecu with a chip for around 350 would be better in my price range. I just wanted to make sure it will handle what I am trying to do. Thanks.

to answer your question.....yes.

and if you haven't already done so, check this out.

you'll notice that you get to control a lot of what goes in the chip. now of course this is for a 1g, but i'm more than positive that you'd be able to do the same for the 2g. if you wanna go with larger cams, just keep in mind that you'll wanna have the idle set to a higher rpm....to keep from stalling.

the dsmlink has advantages yes, but if you're not going with that then yes you WANT the chip if you're going with bigger injectors and to help aid with tuning. there's also forums if you need help, etc.
