basic engine managment

[turbo2nr]

i was going to go ka-t right away with 370cc safc and a fuel pump. but then i reconsidered..

i cant get a ecu tune yet b/c im obd2 (97) i can conver to obd-1 or use a 96 obd2 ecu and have it tuned but ill throw codes i believe. i need to pass freaking emmisions so thats on hold for now.

what i can do is use this setup of engine managment:520cc w/ topfeedadj fprz32 filterz32 maf255 intankmsd btm safc

how far can i get with that? can i hit 300whp safely on 10psi using a t04b?(.63\.58)

i mean a tuned ecu corrects for fuel and timing. the afc only has about 10 correction points so it wont be as fine tuned as a tuned ecu but it still decent. and the msd btm will be set to pull 1/2 degree for ever psi made.

so what do you guys thing? good or bad idea? should i just stick with the 370cc and call it a day?

tHE GOOD THING ABOUT THE safc/BTM combo is that you can simply upgrade injectors without changing a thing. Once you figure out how to run a tuned ECU, you have to pay for a retune each time you upgrade.

I think your 50lbs (=525cc) setup looks good. I dont think the 50lb + SAFC/BTM is unsafe. You can always add the ECU and probably make more power from the better (more flexible) management. The flip side is that you could go with the smaller injectors for now, and add the ECU, MAF, and 50lb'ers later on.

I know the T3/T4 make 300whp at about 12psi, so 10psi on the larger turbine should get you close to your goal. 50lbs injectors are good to 350whp or so. They are the largest size the SFAC can handle

sorry about the caps lock...

do you have any experience with the btm? also does any one know if the safc will be maxed out on 520cc?

also do i really need a adj fpr right way. or can i hold off on it.

Go with emanage with ignition harness. done and done.

I'd prefer to go with a Emanage Ultimate myself. Both the standard E-Manage and the SAFC essentially only tap into the MAF wire to alter fuel maps. The problem is (especially as the injectores get bigger) the ECU will try to compensate when you are not at WOT. With the extra boost you'll want to be running a bit richer. But when you're not at WOT, the ECU will make adjustements using the O2 sensor and bring it back closer to the reading it desires, given the MAF and TPS signal. This can spell disaster under part throttle, high boost situations. You're probaby okay up to 370cc. I'd be reluctant to go higher mytself (though otheres have done it). The Ultimate can completely bypass the ECU's injector signals and add it's own, which would completely eliminate the O2 sensor's feedback. And for smog purposes, the ECU would have no idea anything is wrong and you should get no error codes.

ive heard really bad things about e-manage thats whyi stear clear. but if some on can tell me the what an e-manage can and cannot do, ill look into it. also how much is a e-manage and the injector harness?

also whats the difference between e-manage , and e manage ultimante?

form what i get so far the emanage will allow to add fuel and pull back spark but on a more refined level then what a btm and safc can. am and right? and it wont mess with the ecu.

[Bosrudorfer]

Emanage is way better than SAFC in terms of reliability, etc.

I bought mine for $320 with harness from Marty (Injected Performance)

As for differences I would do a search.

The SAFC and the Standard E-Manage use teh same method of fuel control. The user interface is obviously different as the SAFC uses a handheld display and the E-Manage uses a laptop or an option display with controller(more $$$). I prefer the laptop myself, though it's not s convenient, but once tuned, you really souldn't have to touch it again anyways. The E-manage has a better map resolution and ease of use.

The major difference between the standard E-Manage and the Ultimate is that teh standard used the MAF to control fuel and perhaps can add fuel by supplying it's own injector ground. It can only shorten a pulse by altering the MAF signal. The Ultimate will bypass the OE ECU injector drivers completely. It supplies it's own and shorthens the injector duration by actually shortineing the injector pulse itself. This allows what I mentioned above about the part throttle high boost conditions. It also allows you to use teh full potential of the fuel system. Since teh standard E-Manage and the SAFC intercept and alter the MAF signal, when the actual MAF maxes out, the injectors will not. When I had an e-manage, the MAF would read 5 volts, but the 370cc injectors would only go up to about 84% duration (IIRC) and the altered MAF signal would go no higher than 4.xx volts. You could not hit 100 if you wanted to. This gets worse if you go with even larger injectors. You could add fuel using the standard E-Manage's injector drivers, but the tuning is no longer linear as you have to use another map. Since the Ultimate controls the injectors entirely by itself, the fuel mapping could be done on one map. From a tuning standpoint, this would be the easiest and most logical approach.

Awesome info C-kwik. Can you tell us more about how the Ultimate handles timing?

tubro2nr, I have no hands on experience with any of this (SAFC, emanage, BTM). I'm going off of what Ive learned from others on NICO...

EDIT: I just looked at what the ultimate costs. Its $578 from phase2. Thats nearly the same price as an Enthalpy ECU, which is a better option IMO. Unless, youre driving a 97-98, a wouldnt mess with the Emanage Ultimate.

I use E-manage and it works pretty well. The only thing i don't like about it is the lack of support. If you have any problems with it you are pretty much on your own. There is not alot of useful information out there about it.

I would feel safer with emanage blue. If used correctly it will be far more accurate than BTM and SAFC. You get ACCURATE timing control along with use of injectors up to 640cc I believe, also larger MAFs (Stock one is not likely to not max out at 300hp). Unless you are going emanage, I would say go enthalpy and save your money.
