This thread is to see your scaling maf acording to the mods that you have.

Some people like me, we are looking for a good scale to start depending on the mods we have made. For example my mods are GT3076R, injen intake, saco air filter.

hope your contributions

I use stock scalings. JMF aluminum intake pipe and Perrin filter on stock turbo

I have some problems with the tuning, in idle my mixture is good, around 14-15's in the wideband, in the spool on the ECU AFR is on 15's but wideband shows 12's at full rpm on the ECU have 11's but wideband shows 10's I have some trouble getting the mixture evenly between the wideband and the data that has the ECU.

The numbers in the ECU are just numbers. They will not match the actual AFR you will see on the wideband. The MAF scaling will not cause the numbers to match the map and actual AFR, just adjust your fuel map little bits at a time until you reach your desired actual AFR.

Correct... Sighs...

You are right guys, I Understand, But would be nice if the number on the ecu were something close what the wideband shows so the tuning is more easy, I think that a good scaling of the maf is decisive to do that.

wrong

tweaking with MAF scaling table, you can pretty much get close to map afr. if actual afr is rich, lower MAF scaling at corresponding Hz's, if lean - other way round, raise it

I've matched my map and actual afr within 0.2-0.4 range. personally for me, it's more convinient for tuning, than seeing 9's in map and actual afr being say 11

Ok...without touching the MAF scaling my AFR map is within .2-.4 with just injector scaling
