Title: Tuning petrol engines Post by: nght on January 27, 2015, 02:11:56 AM Hi dears,
I was checking some information about petrol engines this week because almost everything I have seen before was about diesel engines. So I would like to know if someone can help me with some questions. -For a normal tuning on a diesel engine normally you have to touch/check the DW, boost, torque limiter and map limiter (And if going deeper SOI, duration, etc) in that order. For petrol I understand the maps and order is quite different, if I understood it right the order is DW, boost map, fuel map (AFR) right? (And again SOI, duration, spark advance if going deeper) Am I right? Or petrol engines also have a torque limiter? I guess I could self reply this to myself but I have not been able to find the workflow of decisions for petrol engine ECUs :( Title: Re: Tuning petrol engines Post by: TCSTigersClaw on January 27, 2015, 02:40:01 AM It really depends on what ECU you are tuning . Generally there are Torque limiters yes . Spark advance is very important ,not for "going deeper" as you said. ME7 works with Torque model ,you won`t find any boost maps ,fueling is much more complicated than EDC`s too.. :) |
