Is me 100mm maf maxed out?

[Ingo]

Hi

Can some of you experts look at me tune and log and tel me if I need to extend the maf pipe to 115-125mm or can I re scale the maf table for more room on lb/min? this is at 15 psi of boost and I still need to be able to reach 20 psi.

UMMM yes your maxed out at 4600 roughly, you need to scale all the Airflow tables (I suggest 50%) you mentioned running a 100mm MAF bu your really close to the 12,200 Hz limit, I would think you would have more room in the Hz, you may need to get a larger tube as well.

Didn't look at the tune at all, but I hope your PE table was really rich to compensate since you took it up to 6,500. I wouldn't jump on it again till your tuned correctly.

P.S. you running meth aren't you?? And you IDC is 90% so becareful

This tune I did for 17 psi which gave me 11,8 afr but it is around 11 at 15 psi. This is due to hitting the 68 bl/min in the maf table. At 17 psi me maf Freaq is up to 11900 Hz. I ´m running meth as well.

I need info about how I can scale the maf table. If you look at the Mane Spark at the log I´m at max from 3200 rpm to 6400 rpm. Can I rescale that as well to get more room for timing for different psi settings? It is at 1,36 as max.

Will this be fixed with like 120mm tube? Is that the easy way out?

Thanks.

Have a read. You'll find it useful.

Or just convert to the 2.5 bar Speed Density OS.

The larger tube is only going to fix the Hz level, which your actually under at the moment, but a slightly larger tube woulnd't hurt either.

Like I said before you will have to scale all the Airflow tables by the same percent, and then also the spark and trans tables but they shift as opposed to being scaled by percent.

Thanks for this info. It looks like I will do some scaling.

I just scale the map 30% Al sense ok except car is worse to start ( I need to cutch the gas pedal) After this change I can see IDC has gone up and are up to 100-110% but be for they ware 80-86%. AFR is similar. What is the reason for this?

Why'd you scale by 30% instead of 50? That is much more difficult to do IMO.

I did scale 30% to have more sells in the spark table and I thought that is what I need. To do 30% it is bit more time to calculate but that do not meter to me. What is IMO?

Post the scaled tune.

Ok then. That's understandable. IMO= In My Opinion.

This is the file with 30% scale and short first test drive to cheek the tune.
