Official OpenFlash Tablet FA20 Tuning Tech Discussion Thread

@solidONE haha yeah, i know why we install tune, to get more power! but I was a bit concerned about the abrupt engine noise at that 4000 rpm, that was all

I'm happy with the result. I can't wait to get a header and get stage 2 file..

After reflashing to E85 tune, I have killed 2 VQ35 equipped cars. I have AP2 S2000 in my sights next.

Nice which cars?

both mid 2000 VQ's one G35 coupe, and Maxima.

edit:
Add my neighbors Cayanne S to the kill list. I guess my 0-60 times are in the mid to low 5's at the moment.

Quick question. Would the Vigilant CAI be compatible with he current maps or with it mess up the afrs too much. Thanks!

Hi,

I have no idea what spec's a viglinant CAI has however their is a good writeup here on the stock Intake.

http://www.ft86club.com/forums/showthread.php?t=56358

If this vigilant intake changes the diameter of the tube where the MAF sensor sits then its likely to need a specific re-tune of the MAF scaling parameters.
I also believe the stock intake has "straighteners" to smooth the air flow through the MAF some aftermarket intakes don't and this can upset the maf scaling can be fixed but requires re-scale.
It may come with scaling info.

Seems stock intake it pretty good for N/A cars and not much gains to be had by aftermarket intakes.



The consensus appears to be add

1. A quality drop in replacement filter
2. Maybe a "perrin" intake tube (only cause I have seen dyno results from a couple of sources that show small 2-3 whp gains) and it removes sound tube.
3. Cut the stock intake snorkel down and expand inlet (there is a how to do guide somewhere)

These simple cheap mods would appear to get results very close to any aftermarket intake system on an N/A car

Checkout the Grimmspeed intake thread in the exhaust section...

Right now they are testing all kinds of setups including stock, modded stock and different intakes.

If you can, go back to the stock Intake and modify it. Then sell your old intake to help pay for the OTF. Win, Win

I already have an OFT and running a Stage 1 map. I was just looking to see if I could get a better flowing intake. Specifically one that has the filter located inside the bumper instead of sol close to the engine. But I will not purchase it if it will negatively impact my performance.

Remember the stock intake has a snorkel that draws cool air in. Also Shiv bases his tunes with the stock intake due to the MAF scaling. On this car, intakes are a waste. I would just modify stock setup, and get rid of the sound tube to clean up the engine bay. I am getting rid of my aFe Intake and going back to stock to get the most out of Shiv's tunes and to be safe.

Are you referring to a vibration noise? If so, I believe I've isolated the source at the overpipe heat shields. There are 5 pieces of the assembly in total not counting nuts and bolts. There are upper and lower sheet metal pieces at the front portion and rear portion plus a clamp that holds the 4 pieces together onto the overpipe like a hose clamp. Unfortunately you'd have to unbolt the pipe to remove the front upper piece. I tried and I have a deep cut on my thumb and some scuffed paint in the engine bay to show for it...

I covered my stock air box and intake tube in heat reflective aluminium tape cost about $10 and reduced intake air temps considerably on hot days in traffic, so much heat radiated from headers int these motors

[smbstyle]

Is there any mounting solutions out for the OFT to keep an eye on live data while driving or on track? (i.e. oil temps, water temps, etc?)

[tonystewart]

The FA20club CAI works very well with OFT v1.54 EL header gas tune. I will data log next week to provide IAT's with this tune. Previous data logging show only a two degree differential

A cell phone holder would probably work. The kind that looks like a clamp.
I'm assuming you'll need one for a large phone, like a Note.
