I have a 2002 WRX with a PDE uppipe and PDE catless downpipe with a STI exhaust. I run the Stage 2 base map and Stage 2 real time map but use the 91 octane because I did not want to chance any detonation.

Hawaii fuel is rated 92 octane which is a higher octane rating than the 91 map requires but is 1 octane lower than the 93 octane map.

Does anyone have a similar set up as me that run a 93 octane map? If so do you have any problems with "pinging" etc.

Also, how long have you been running with this 93 octane map.

Thank you in advance for your feedback.

I dont remember what OTS map i was running when i had my AP since it did not stay on there long but if your really worried order a email map from pdx i think its like 150$.

 

you got it right. the 91 map should be fine. i ran stage 2 on my 07wrx with the 91octane map. for a long time. no problems what so ever.

 

Don't run the 93octane map...run the 91 maps if your are using the free Cobb STG2 maps.

Many of us bought the PDXtuning.com over the counter maps...Jarrad has it pretty much dialed in since he has tuned so many of our cars here. His tunes are for Hawaii's 92octane premium.

$150 is pretty cheap for a semi-custom map...and it is a very noticeable difference from the over-conservative Cobb maps...

 

Thank you everyone for your sound advice.

I will leave my map at the 91 octane or if I do change it it will be to something like the PDX map.
