So I have a 2010 Evo GSR and purchased the K&N Typhoon intake system and then decided to purchase the Cobb AP. I soon found out that there were no maps for the K&N intake. After a little but of research I found out that because the K&N intake still retains the stock MAF housing you can get by with using the "Cobb SF" intake map. I have had the Cobb Sf intake map while using the K & N intake for 2 days now with no problems and I have been watching the knock... Any input if this is okay to do?

 

Shouldn't be a problem.

 

So you think it will be fine?

 

You should be fine just keep an eye on it

 

Do you think it will be fine because of the same sized MAF or because the intakes/ intake tube diameters are all pretty much the same?

 

Should be fine due to the stock MAF housing. If boost and knock check out then you're good to go

I took your recommendation Kracka and picked up the Typhoon for my 2011 GSR. I've had the BETA Stage 2 map on for a week with no problems. I'm getting lower knock counts vs stock. Still getting phantom low rpm low load (so all good)

Thanks again Kracka. Still working my way up to E-85 then FP

 

So you are running turbo back exhaust as well then? What counts of knock are you getting around like 2500 rpms? Cause sometimes I am getting like 9 counts of knock around 14k-2k rpm.... like 1 of every 15 start from a stops...

 

Some time shifting and stopping and going will give you "knock". What you really need to watch is what your getting during normal driving/WOT pulls. If you are getting high knock, try using the stock box maps. They worked to me with the ETS.

 

Yeah, I am getting ZEROOO knock when I am pulling... So it probably is just when i was stopped and shifting again. Im not over boosting and everything checks out! So im guessing the trial is somewhat of a success!

 

Yea man just keep a eye on the knock, do a test every once in a while, and i would suggest getting a AFR gauge sooner then later.

 

the low load; low RPM knock is usually engine noise (check for vibrations). Use your Cobb AP to monitor your stats and log in to Cobb forums and let Braden take a look at your logs

 

Hey guys looking for some input, I have a typhoon intake system and am running stage 1 93 cobb sf map. I am getting 1-4 counts of knock past 6500 rpm. I changed the tune to the stage 1 91 cobb sf map and still get 1-2 counts of knock past 6350. Here are the maps, first one is sf 93 oct 4 gear pull to the red line, second one is sf 91 map with 3 gear pull to about the red line. I have read that 1-2 counts are nothing to be worried about....what do you guys think?
