Hi All

I just fitted a ARC FMIC Kit yesterday and the power feels more smoother but no as great...the kit was second hand, do you think that there could be a hole in the cooler or hosing, or do you think its just my imagination...any help would be great...and yes ive double checked the clamps and they are super tight....cheers

Hi All

I just fitted a ARC FMIC Kit yesterday and the power feels more smoother but no as great...the kit was second hand, do you think that there could be a hole in the cooler or hosing, or do you think its just my imagination...any help would be great...and yes ive double checked the clamps and they are super tight....cheers

I've had a small hole in my cooler before. You definitely know when you have a hole in that you can definitely hear it even off boost.

not vacumm but boost seems a little low (still at stock) but feels not a hard to kick in...i didnt know if this happened when fitting a fmic or not

Whats your vacuum at idle? should be around -500 ( reading of the PFC hand controller on mine)

Umm I am definitely no expert... but it just sounds like the bit of extra lag you get from fitting a FMIC and all that piping compared to the stockie???? Normal I thought - hence why u normally combine the FMIC with mods like a full turbo back 3" exhaust and a bit of extra boost etc to balance out the lag... the FMIC istself doesnt do much for performance - but creates a cooler environment to allow you to fit more mods and up the boost with less risk

Personally I wouldnt do a FMIC if you werent modding up - but then again thats just base on other reading in here - so i could have it completely wrong :rolleyes:

i will check the vacumm next time i start up...brazen cheers , but i have a 3inch system

Yeah - but whatever mods you have - at the point you install a FMIC you will get an increase in lag over what u had before the FMIC... did u have a FMIC before and just swapped to a Blitz system - or go from stock sidemount to FMIC?

Yup - thats all it is - you've introduced a bit more lag with the extra length of intercooler pipe - so it'll feel a bit more sluggish - although your peak performance probably hasnt dropped - just changed your curve.

The FMIC just now will allow you to do a few more adventurous things to up your power and push it power back down the curve a bit - whereas pushing a bit more with the stock cooler would start getting risky further down the track... talk to your tuner... but the FMIC and maybe a couple of extra bits and pieces should now let you up your boost if you so wish or do more hardware mods. It wont take much now to get that lag out of the way and make the car FEEL fast again :(

if the cars stalling, from my experience, the fmic should have nothing to do with this saga..

perhaps, check with your tuner about these few things..

- b.o.v could be leaking,

- fuel pump maybe earthing

- if its a series 1, rb25det, check you coil packs & the ignitor pack above the #6 coil pack

- crank angle sensor maybe ****ed, & might need replacing

* my car did this, i though the b.o.v maybe leaking, but that wouldnt cause your stall

- my cars crank angle sensor was not sending the right signal, & the ignitor pack was ****ed as well, ive replaced both c.a.s & the ignitor pack ( as we speak its in shop) & the mech said thats my problem, maybe yours too...these are just a thought...

    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
