F/IC Installation Notes: Honda Civic 06-07

[SB]

The F/IC has been succesfully installed on the 2006-2007 Honda Civic. We have tested with the 2.0L Civic Si and the 1.8L Civic.


Please note that the Civic is equipped with both a MAF and MAP sensor, so you will need the new Version 2.01 FIC software. The old software will not allow you to clamp both the MAF and the MAP signals. The new software can be downloaded here: http://forum.aempower.com/forum/index.php/topic,20726.0.html


Also note that the OEM ECU is installed in the engine bay. The FIC is not sealed from moisture, so it must not be installed in the engine bay.


Here is the wiring diagram:

What any difference between  wiring diagrams for 2.0L Civic Si and the 1.8L Civic  ?

Whats about O2 modify maps ( closed loop AFR target) and any setup notes   for K20 and R18 setups ? More interest for R18 setup, please.

Thanks

[SB]

The R18 motor has one cam position sensor, and the K20 has two. That was the only difference we found. Our test vehicles were both turbocharged, so we weren't able to log base values for the MAP and MAF sensors. If you would like help setting up the MAF and MAP tables, please attach an FIC datalog including a few full-throttle pulls from a bone-stock Civic.

Attached is a copy of the O2 sensor info:

for anyone who will be using the f/ic     http://www.boomslang.us/aemfic.htm  has the harness for plug & play

I have seen on ivtec engines that inlet cam timing has big efect on engine power,
As is fic retard the inlet cam signal in relation to the crank signal.
I think a separate control for the inlet cam signal  +/- comparing to crank will be very helpful for all the new ivtec/mvec engines.
Any plans for the future??

Not likely, although I agree it could make a big difference in power if tuned correctly.

any update on this is working on the car

[SB]

Yes, the customer has been to the dyno and was happy with how things turned out. That was a couple of weeks ago, I haven't heard from them since.

hi, i've  a couple of questions pertaining to the R18 setup:

1. has anyone tried this on a stock R18 yet?
2. must we use both the MAP and MAF sensors on the R18? i.e. without any turbo? just NA?. Would either MAP or MAF do? or must both be used?
3. why must we tap TPS?
4. why must we intercept CMP?
5. Is the  CKP is spliced into for the purpose of timing retard? if we don't intend to retard timing, must we still cut this wire?
6. why must we tap multiple power and signal ground?
7. what is rpm signals based on? CKP or voltages?
8. does anyone have a base file .mdb for the R18 stock NA engine?

THANKS in advance!

[SB]

1. Yes, we've been in contact with a shop that dyno's a turbocharged R18.
2. The stock ECU will throw codes if the  MAP and MAF sensor values are too high. The FIC is used to clamp them and avoid check engine lights.
3. TPS is for reference & datalogging only, not required for the FIC to function.
4. The FIC adjusts the timing of the CKP signal in order to retard timing. Some factory ECUs compare the CMP and CKP timing to detect knock. For this reason, the FIC adjusts the timing of the CMP signal as well.
5. Yes, CKP is intercepted to retard timing. If you are not planning to retard timing, you can tap this wire instead.
6. Multiple power & ground wires are used for two reasons: reduncancy and higher current (amps) capability.
7. RPM is based on CKP frequency.
8. We did not test on a stock engine. If the car is completely stock, the FIC's base map should work just fine as long as the harness is wired properly.

Note that the bypass plug supplied with the FIC will not bypass the Analog A signal properly. The bypass plug was designed before the FIC's software redesign. You will need to cut and splice the bypass plug so Pin 3 connects to Pin 6 on the 24-pin connector. This will allow the bypass plug to work properly.

Hope this helps,
SB

Thanks SB!!!

2 more questions from me.

1. When you say it'd work alright for a stock R18 (non turbo) with the base maps, do you mean with everything set to default e.g. maps are all zero-ed (0)

2. Has anyone used this to tuned the AFR on a stock R18 and maybe some adjustments on timing to gain performance on a non-TC R18?

Cheers!

Great info!

[z0n3]

er.. any updates anyone?

i have a R18 iVTEC (2007 model) NA, and I want to test it with an INJEN intake and Aftermarket Exhaust.

Stock is rather lean below 3,200 rpm (15.x)
Stock is pretty rich from 3,200 rpm onwards - 12.x

As such, I'd like to lean it out from 3,200 rpm onwards without affecting the ignition timing.


But the big question on my mind right now is whether I should use be tapping on the MAP or MAF for fueling changes on this NA R18.

Any suggestion?

Cheers!

[z0n3]

er.. anyone tried this on a NA? thinking aloud..

If i don't plan to put turbo on my ride, then i just need to tap (no need to intercept) the MAP or MAF right? Since MAP or MAF will be primarily used to determine load... and I don't need to clamp any signals.

and the fuel injectors wiring will be intercepted to change the fuelling.

Is that right?

As such, I just need:

a. ground and power wiring (tap)
b. MAP or MAF (tap) - for Load sensing, if I don't intend to clamp signals
c. injector wiring (intercept)
d. crank position sensor (tap) - for RPM sensing, if I don't intend to retard timing.



SB, can you explain this again?
"Note that the bypass plug supplied with the FIC will not bypass the Analog A signal properly. The bypass plug was designed before the FIC's software redesign. You will need to cut and splice the bypass plug so Pin 3 connects to Pin 6 on the 24-pin connector. This will allow the bypass plug to work properly. "

I'm a little lost.

in the picture, the short term trims figures are progressively higher as it richens up.. is this on a stock Civic or on a boosted Civic?

[SB]

This was a boosted Civic, the test was performed at idle. The "trims" were displayed on an OBD scanner, there were no adjustments made to the FIC's fuel table.
