fuel mods or cooling

[95redtransam]

Hey everybody im having a really hard time deciding what to do here. I cant decide what would be the next best thing to buy for my car. Im looking at getting either a good FMIC setup, or fuel mods. I would get AFC, 660 injectors, uego wideband, fpr, all at once. What do you think is more important right now with the mods I have? If I did get the intercooler now, would I feel a difference or would it just be good to have for after the fuel mods and cranking up the boost. Heres my mods

95 TSI fwd
3 inch turboback
injen intake
dejontool uicp
1st gen bov
255 pump
Act 2100 clutch
Evo III GT Turbo (Which is working awesome) 15 psi
boost & A/F guage
New tires

Thanks

Build up your fuel system first then go for a FMIC. I say this because without a good fuel system you won't be able to take full advantage of that turbo.

I also say fuel. Espically with a 255 on a stock fpr, that thing is going to make you run so rich. I don't think for 660's you necessitate a wideband yet, but I myself am not far into tuning so i don't know the +'s and -'s for them. But im sure you'd be fine running the 660's with the an safc. maybe instead of a wideband think about a maft setup? so you could further fine tune, or at least have a couple different ways to go about it.

as for the fmic, if you're running a e3-16g only at 15lbs you're fine on stock sidemount for now. I'd maybe push the boost a little and log some passes to see if you're running any knock and also check if you're heatsoaking the sidemount.

Wideband is always a good idea no matter what your fuel setup if your trying to get the best possible tune & doing it yourself. I would agree with the others and go fuel first. There's no point in getting a nice fmic if you can't turn the boost past 15 because of lack of fuel. With a stock smic, & the fuel upgrades you should be able to turn the boost up to about 18, just make sure you use a logger so you know your not knocking. Since you have a 95 and may already have an eprom ecu have you thought about going dsmlink instead of the safc/logger combo? Abit more money but well worth it & is simple to understand even for new tuners. When you save up some cash again & get a fmic, you'll notice a nice power increase when running 18+ lbs of boost. Thats when your turbo will really wake up & you'll have some fun.

I say if you have all those mods then you are going to upgrade that turbo at sometime. So get most of the fuel mods. But instead of a wideband and a SAFC, get DSMlink.

Also get as big of injectors as you will ever think you will need, I would say 1000cc's just to cover every base and then you can comp for them with DSMlink and you will be oh so happy.

ANd the reason I say go big on the injectors is that a guy in Indy has a big 16g 720cc's and is running them at 72% at 26psi, so just go big on the injectors get the link and fine tune everything for no know.

I agree that you should replace the SAFC with DSMLink but you should keep the wideband on your list of things to get. One of the easiest ways to get a good base tune is to use the O2 sensor. Obviously, the more accurate the readings, the better the tune. In terms of WBO2 manufacturers, I'd suggest Techedge, which is an Austrialian company. I also agree with ian that you should get bigger than 660. The last thing you want is to upgrade your turbo and discover that your injectors are maxed out. You should go with at least 750s to give yourself flexability for the future.

Ok thanks for all the replies. Can somebody tell me how I can tell if I have an eprom ecu. After reading this im starting to lean towards DSMlink. I just dont really know how it works. I am also leaning towards 750 injectors. I do think that a wideband is good to have. I woudn't need a logger or anything else if I got DSMlink right? I really want to max this turbo out and then stop there. Im thinking after these mods and fmic I would get cams, intake manifold, and whatever else is left. But......Ill probably do like most of you guys and go bigger eventually.

If you go the safc piggy back route, don't go bigger then 650's as you will add too much timing because of the fuel compensation. If you go Dsmlink, like has been said go big so you dont have to upgrade again. I run 750's with my evoIII and at 18 psi see about low 60's % duty cycle. I would recommend 850+ just in case. With dsmlink no you don't need a logger, its built in. All you need is a laptop or some use a palm. To check if you have an eprom ecu, pull the ecu from the car. On the part # sticker look for an E in the lower right hand corner. This is to tell you its eprom. To be 100% sure, pop of the cover, when holding the ecu so all the harness plugs are at the top, look for a chip thats about 1" by 2" long in the bottom right corner of the board, this is an eprom chip. If that chip is there, your set and just need to send the ecu out to get socketed so you can easily swap in the Dsmlink chip. If there is no chip there, then your out of luck & need to pick up an eprom ecu. In case your wondering, no a regular ecu can't be made into an eprom ecu.

Almost all 95's have an eprom. here's info on a 1g. I don't know. Mayby you can see a similar chip in your 2g ecu. Chances are you have an eprom already. You lucky SOB

To get a better idea of what DSMLink is capable of, go to www.dsmlink.com. One very nice bonus to using DSMLink is you get access to the incredibly good DSMLink forums which are great especially for advice on how to tune with DSMLink.

fuel and dsmlink... trust me i put my fmic on and already had dsmlink, and i was overflowing my maf and running out of injectors (100% DC) by 4300rpm. Get the fuel first and when you get the fmic/intake you can turn the boost up and run it to its full potential!!!


hope this helps
