Title: Re: Ibiza Cupra with 440cc injectors Post by: aef on August 25, 2014, 04:29:56 AM i did not download your KP but KRKTE should be at 0x18C6B
Have a loot at your part throttle value in block 032 to alter krkte until 0% difference which injectors (part number) are we talking about? Title: Re: Ibiza Cupra with 440cc injectors Post by: Roader55 on August 25, 2014, 08:34:37 AM Bosch green 440cc,yes KRKTE is the same adres,but on channel 32 there is nothing i look at channel 2,there is the fuel trim :) with stock injectors is close to 0,but when i put 440cc it goes to 25 and car smoke really bad black,i try correct this KRKTE but nothing happen
Title: Re: Ibiza Cupra with 440cc injectors Post by: bk56190 on August 25, 2014, 12:44:44 PM You have to decrease KRKTE with bigger injectors, not increase it !
Try 0,0726 and adjust with fuel trims. Title: Re: Ibiza Cupra with 440cc injectors Post by: fknbrkn on August 25, 2014, 12:52:00 PM probably you need 0.0758 not 0.758
Title: Re: Ibiza Cupra with 440cc injectors Post by: Bi-turbo on August 26, 2014, 03:17:13 AM Just on a side not the "green top" 440cc injectors dont work well with 20vt's i went to use these and opted for genisis 550cc in the end, green tops are like a water tap compared to the genisis 550's. you may struggle to get a good idle and "off throttle" fueling
