Title: Help please! ME 3.8.3 maf & injectors. Post by: checcoa3 on July 24, 2013, 04:24:20 AM Hello guys,
I am writing because I need your help. I'd be very grateful. Should I tune my ME 3.8.3 with the following changes: -maf housing with 72mm id -350cc injectors. I currently have a k04-022. I have read a lot of information and I did many tests but I can not tune the engine. the engine idle is too lean I have a AEM wideband probe to check the stoichiometric ratio. I tweaked the following curves: - Grundanpassungsfaktor 0 - Linearisierung der Heißfilmspannung - Spannungskorrektur any information is helpful! can you help me tune. Title: Re: Help please!

Title: Re: Help please! ME 3.8.3 maf & injectors. Post by: checcoa3 on July 24, 2013, 10:08:37 AM I have done many tests and I was going crazy to delete the map.
however, the change I made is as follows: - Grundanpassungsfaktor 0, set to value 77 (original is 128) - Linearisierung der Heißfilmspannung, I interpolated from -7% to +35% Title: Re: Help please! ME 3.8.3 maf & injectors. Post by: checcoa3 on July 26, 2013, 12:28:47 PM I ask you guys for help.
continue to do tests ... the only way to lean a little is the lambda ... Title: Re: Help please! ME 3.8.3 maf & injectors. Post by: Roader55 on August 04, 2013, 05:47:43 AM you mean the lambda map? where you get with test?
Title: Re: Help please! ME 3.8.3 maf & injectors. Post by: checcoa3 on August 04, 2013, 12:08:36 PM you mean that.
I'm now a limiter to about 12:1 stoichiometric. Title: Re: Help please! ME 3.8.3 maf & injectors. Post by: jokerr9 on August 31, 2013, 02:36:48 AM And what about FKKVS - Correction factor for fuel supply system(from me 7.5)?
I can't find it in me 3.8.3 I'm going to replace my 260cc(AGU) injectors with 317cc(AUQ). I've changed 1. Fueling constant: Grundanpassungsfaktor 0 2. Start fuel inj time(ms): Startgrundmenge (2 1x1 maps) - copied from AUQ 3. Spannungskorrektur - copied from AUQ And should I change Spannungskorrektur if I'll just install 4bar fpr with 260cc? Can't find specs for these injectors(bosch 0280150464) wth 4bar pressure. Thanks. |
