In the past 2 weeks, I tuned a local Dezod S1 on a GReddy E-manage blue and last week I was out in PA tuning a Dezod S1 turbo'd tC with an AEM FIC.

The E-manage car was tuned entirely on the streets and highways here of Buffalo. The car was truly an on/off car, which is typical of the e-manage. Either your cruising in vac or pedal to the floor. No real in between to be safe.

The AEM FIC car was entirely street tuned on winding and hill roads mostly in the country where he lived. Car had good street manners and definitely impressed the customer and his father who had some fun too. Overall the FIC behaved well with no faulters or hiccups. We drove the car for 5-6 hours that day and then they drove me back to the airport the next day which was an hour away. The car was a champ for being on a piggyback.

In comparison to an 08 tC I did on an GReddy E-manage, the AEM FIC performed much better, but both where of no caliper of the AEM EMS.

E-mange Pros:
*The e-manage did not have stop light "hunting" at idle as much as the FIC did.
*The e-manage anti-stall worked well when programmed properly
*Easy to setup in tune in comparison to AEM FIC
*Took about 2 hours to complete from scratch

E-manage Cons:
*Ignition retard did not work well at all
*Truly on/off no partial throttle correction for boost

AEM FIC Pros
*Had decent partial throttle control (not 100%, but had more than the e-man)
*Had great ignition control

AEM FIC Cons
*Harder to setup and get right
*Lots of maps for a piggyback
*Constant fuel trim monitoring
*Hunted pretty bad at idle sometimes

Overall, neither car stalled in my presence as a result of an open atmospheric BOV (which so many people are programmed to believe)
---The FIC customer stalled once or twice on his adaption to the S4 CC clutch he was driving.

The ST fuel trims I was able to get to zero and give the turbo what it wanted and the stock ECU the same. The LT fuel trims, when I started where up in the -30s, by the time I ended, the closest I had gotten it was -20. Figured I would share

 

When you get short term fuel trims close to or at zero, it'll take time for the long term fuel trims to adjust. I've noticed it can take as long as a week for long term trims to behave properly and still have short term trims at/near zero.

 

nothing.. NOTHING beats the AEM EMS.. By far worth every penny!

To anyone who is in denial, Dont be! this computer is the way to go as far as a scion goes!

Thanks to dezod for making such a great product!

 

paul man....how are you watching knock when your street tuning?...id love to know

 

He rolls down the window and listen to the engine for detonation.

 

nice paul...i like comparisons like this...

 

minor thread jack here hey paul im running an s1 kit i need to replace my spark plugs what should i gap them to

 

since it's been jacked. i got a quick question for you paul! do you by any chance know how to data log your AFR's with a UEGO and FIC? i have the PnP play harness.

 

Is there any way to fix the idle hunting paul? mine is terrible and i would like to get it worked out.

 

Don't you already have a comparison on your website?

 

i think they do....lol
i was talking about the real world comparison.

 

i was told by dezod 34 - 36 is okay for spark plug gap. but i'm getting spark plug blow out in 4th and 5th with them gapped at 34. i'm assuming its the altitude. i'm going to drop them down to 32. once i get off my **** that is.

 

crap i feel stupid for having mine at 29 all this time....lol

 

meh i might take them down to 30.

 

I was told to gap mine between 28 - 32 (not by Dezod).

 

Check out AEM Power Forums. They have a whole writeup on how to in the FIC section

26-36 is my recommended gap for a turbo tC

 

This is complete and utter real world close time proximity, which REALLY made be hit home and recall the extreme differences to the community.

 

Yumm.

 

how does the F/IC stack up against the E-Manage Ultimate rather than to the Blue? Thanks

 

It's not in the same league as the Ultimate.
