Tuning fuel Map 2.1
Hi guys, i have some questions with the first 2-3 log i did last night, i will do my best to speak a decent english .
It is normal to be lean 16/1 +during gear shift ? Now a basic question, does the way to calculate total engine load is with the rpm and the map ? what about full throttle application vs half throttle aplication ,does it change the engine load ? |
I will try to explain my last question better.. when someone say: u can add 10% fuel between 60% to 100% load( between 3000rpm and 7000rpm), Does my 60% load start at 6psi, if my maximum boost in this particular case is 10psi ?
When talking about maxing the corection map , does it mean to add fuel for your setup more than necessary first? If i get it , after 'maxing my corection map' i can do my log/tune slowly in 2nd gear with part throttle first, and at wot when safe , and THEN slowly when i am happy with the a/f ratio i have in all gear, i can lean the fuel map corection table to obtain the a/f and the driveability i will like to have. |
The fuel table is RPM vs Boost. There is no solid connection between load and boost. Every car is different. If someone says "add 10% between 60% and 100% load" they also have to provide a complete list of mods to quantify what "load" is.
It's always better to start out with too much fuel than not enough. That's not to say you should "max out" your fuel table and start there! Lower the boost, and see where you are at. Slowly raise the boost and make adjustments as needed. |

thank you very much.
I have now the plviewer all set in my computer , i am not able to calibrate the wideband sensor into the plviewer ( i have read the plviewer userguide ) . My wideband sensor is well calibrate into the pocket loger software , heres 2 pics https://cimg3.ibsrv.net/gimg/www.rx7...43a30aaf2b.jpg https://cimg5.ibsrv.net/gimg/www.rx7...d47c32de1b.jpg I did last week a fuel pump rewire and the difference between before and after was quite important , voltage at pump was low before and now its rock solid 14 v. a/f ratio are WAY richer now i am realy happy about that . oK now when i log the 'secondary' parameter it stay off all the time even when at 5000 +rpm .. so it seem that my secondary inj are not firering what u guys think about it? i have brand new inj dynamic 720 cc in , so i guess i will be traking this electrical prob in the near future. |
