Hello people, I would like some input on what tune to run for my setup. Here is what i have.

K24 block

Blueprint rods
K20z3 head with blueprint port and polish

Brian Crower stage 2 cams
Brian Crower Dual valve springs

Any input is appreciated.

i was told the k20a2 with crower stage 2 cams would work with some added fuel and some a/f tuning.. I only want a tune that is safe to break the motor in with some highway driving. I want to get it tuned the first week of april.

Thanks

is this the same user i see on k20.org all the time? if so what up dude , haha.

here buddy , load this on there do a datalog and post it up. i can help you if you like. this is the stag2 crower map , added 5% fuel to entire map , took out 2 degrees timing from WOT columns. lowered cam angles more suited to K24 bottom. try it see what happens , while your datalogging , keep an eye out for knock count and lean conditions. i didnt enable lean protection so. listen carefully for spark knock while driving. not just WOT , but cruising as well.

Map worked great.. Im just getting a pretty rough idle.. Im not sure what to change to help it out. Ill see what i can do to get a datalog up on here for you to see.

Here is an idle datalog and a 3rd gear datalog..

I did the recommended fuel adjustments in the 3rd gear log.. Any other pointers would be great.

what recommended changes? lol. here load this on. do a long datalog , vary driving conditions. make sure its in open loop. keep an eye out on the A/F. you really need to wire in a knock sensor. do you know what spark knock sounds like? lol

02ep3si · Post by **02ep3si** » Wed Mar 25, 2009 1:45 am

yeah, I know what spark knock sounds like..

My knock sensor threw a code when i was out so i disabled it. Do you got any ideas on a better sensor to put in there?

How long of a datalog do you want?

Thanks again for the help.

at least 20 minutes. you should really get a knock sensor in there and functioning. make sure its in open loop. watch your A/F.

you didnt answer me , what changes did you make? if you want me to do this , dont make an changes ok. or at least tell me.

use this for the datalog

sorry i was out of town.. Ill get to the datalogs tomorrow night i hope. What i did wast a 3rd gear pull and did the a/f tuning using the lambda overlay.. i had to remove a little bit of fuel across the wot map...

i will get them using the new kal you supplied.
Thanks

you cant tune using overlay. you can reference it when part throttle tuning but not WOT.
