ECUtek>s-afc.wat hp gains?
ok right now i have an apexi s-afc, and i am getting an ECUtek. i never knew how much hp i was losing!!!(lots)!!! i have aton of mods done to my car, heres a list:
-bushcur racing 20g turbo
-turbo xs fmic kit
-injen upper intercooler kit w/ intake
-megan racing headers
-taipan xp tbe
-walbro fuel pump
right now i was dynoed with the s-afc with 313whp, and the place i was tuned said i should have ALOT more so i am buying an ECUtek and getting rid of my s-afc. they said its hard to think about how much hp i was loosing with the s-afc. well i am geting the ECUtek installed and dynotuned next week. and i was hoping some1 cud help me out and tell me how much more hp and trq i will probly gain with the ECUtek? can u please help me out, i just want to make sure the gains will be suffient and i will get a nice increase. please reply with ur thots on hp and trq gains.
thank u, sean

You guys are lucky - the temperature, ambience and sea level could draw you such high whp.
I only gotten 298whp on stock e9 turbo with ecutek. The most i could get out of burchur's probably 330whp.
now i'm running apexi ISAMU RX6 upgrate kit (for evo9) with Ecutek - only gotten me 350whp! And mine has already having fuel, injectors and delivery related equiptments upgraded. Getting HKS Mivec 280 cams by end of months. Will see if ecutek could properly tune my new setup. One thing for sure, I can't reliably tune ecutek beyond 2bar due to MAF restriction.

ECUTek is a reflash.. You mention getting it installed, Are you sure your not talking about a UTEC?
In either case The gains are hard to guess, we don't know how well your car was running with the S-AFC, but its likely it was getting a bit of knock, and not running optimum timing, so there would be a difference.
Once you have direct control of your fuel and timing maps, the gains will be quite a bit better with a good tuner.
Now here's the interesting thing, the AFC might actually not have been all that bad on power, the problem is the lack of control you have over timing as the adjustments indirectly affect airflow which alters the ECU's percieved load. Its just old school.
If you are indeed getting an ECUTek reflash, then you don't have to remove the AFC, just have them "Zero out" the settings.. as having it will allow some future adjustment should it be needed without having to reflash the ECU again.
Different dynos and even the same brand dyno in different shops will read differently, so its important to get a baseline before you make any changes so you can see the actual gains. I know of many people who were disappointed when they were originally dyno'ed at a shop with a high reading dyno, then tuned at another shop that read lower. The gains were there, but they were hooked on those numbers.
