^^^ this.

If you got mad blow-by, it's time for a new engine

[loki]

As I've mentioned before, I've noticed that my fuel economy really went to shit once I switched over to the V200 map.

Cobb set the max load before switching to open loop to 1.0. I always believed that the car was going into open loop too easily, as my car hits 1.0 load very quickly in everyday driving situations, so I monitored calculated load one day and confirmed this.

I have since switched max load from 2500rpm and beyond to 1.13, and below 2500rpm its set at 1.10. My fuel economy has gone back to what it used to be, and I'll be monitoring it to see if it stays that way.

I also adjusted my throttle tables and changed the APP translation tables to a direct 1:1 ratio, and I like the way the car feels. Very stiff pedal now and I feel like I can feel the car alot better.

Edit: wife took the car out tonight and came back and told me she likes the way it drives now compared to before. So got wife approval! Nice.

my fuel economy is total shit on v200 too... this is very good info. curious to know if you find any downsides as you log further... e.g. time to hit target AFRs as you mash WOT

[Fack_Dude]

Nooooooooo you let the wife drive the car!!!!!!!!!!!

my wife probably drives my speed more than you drive your speed. She's good like that!

To be honest, when I was running the V108 maps, I had the max load to exit closed loop set at 1.25 as per Abilor's guide and didn't seem to have any problems then.

Wife approval = win.

Fix the shiner on your car yet?

Is it possible that your car is running better and thus you're pushing it more? I have not heard anything from the relatively larger user group on MSF reflecting this.

slightly richer afr's aside, from my experience, the only reason you get worst fuel economy is from flashing maps and pinning the throttle...

I thought so too, but I haven't been driving it hard, and I even tried babying it on the throttle and still it wasn't just guzzling. Obviously the more you mod, your fuel economy will take a hit, but I hadn't done anything except change the map version.

As far as MSF goes, I figure alot of those guys have pretty heavy mods anyway and their fuel economy has gone to shit anyway?!? It's hard to tell. It's just something that I noticed, and a bunch of the other guys (horto and mr wilson) also have noticed a difference once the v200 map was flashed.

I can not dispute your personal user experience of course and I'm interested in your observations. Let's discuss.

The 1.00 load commanded by the OTS maps are not linear across the range, first of all, so if you leave the OTS values, notice that some of them venture away from 1.00. Having said that, the amount of real time in tenths or hundreths of seconds it takes to go from 1.00 to 1.10 or even 1.25 is very little. And comparing that between 1.00 and 1.25, the only difference should only be felt through driveability...and not necessarily long term fuel economy, unless your digital toe can keep 1.1x+ load consistently...lol...which leads to the observation it's just you stepping in deeper into the throttle.

Which brings up another possible difference is in your throttle mapping. If you've made your throttle more agressive, you may still be judging your fuel use by how deep you're into the gas, but that depth now may equate more throttle?

My point is that I did not notice that the v200 maps had significant changes in the tables that may affect long term fuel economy. This is of course, espcielly true, if you kept all your MAF and fueling tables from before switching over.

[loki]

I only made this observation because I do alot of highway driving for my job, which means not much chance to gun it when going on long 300-400km round trips.

Tomorrow I'll be driving to Stratford so will see how that goes. I only base fuel economy by how many kms I get per a given amount of fuel. Given the long trips I make, it's a pretty consistent way of monitoring how the car is functioning with respect to fuel economy under light loads.

which tables were you referring to in the OTS map? It'll be easier to follow what you're saying with ATR open.

The only tables I'd say that affects fuel economy most would be a calibrated MAF...all the fueling/AFR tables...the throttle tables...

The othe thing is...eventho Cobb commands 1.00 load for OL, it doesn't go into the 11's right at 1.00...it think the OTS map I saw still didn't get into the 11's until like 1.78 load.

Before I adjusted the tables, I monitored the AFR's and mine went into the 11's very easily. Though I haven't checked the AFR's now to see if there's any change, and you can only see one variable at a time. So no clue what the load is at the same time....

my LTFT's are all over the place (-10%) and have been since we cleaned my MAF. I will have to do some MAF calibration logs tomorrow on my way to work.

[Fobio]

"-10% LTFT" means the car is putting in 10% more fuel than it needs, and it's PULLING 10% out. That might be it.

well we'll see what happens when I calibrate the MAF tomorrow.

While we're having a discussion, if I try to run through the gears (to redline), 1st , 2nd, 3rd the car will pull back hard . Any thoughts?

what kind of pulling back are you referring to?

I think you need me to drive your car for good measure...and no, I don't men that in a naughty way...hahaha...

I think thats a good idea

side note: koni yellows have been ordered!

[BlueStreak]

That'll definitely improve handling. Awesome.

that's what I'm hoping for.

ordered Tuesday night and should be arriving either tomorrow or Friday

[BlueStreak]

From Nextmod? That must be a record for them.

EDIT: Ugh. Spelling/Grammar. Must start proof reading...

[loki]

From Nextmod? That's must be a record for them.

Hahaha no definitely not nextmod

[loki]

Hahaha no definitely not nextmod

koni's are in and have been collected.

thanks Alphamotorsports!

now to bug Jimmy to get him to put them in.....


edit: Stage 2 meth kit priced out and ready to be ordered for spring. sigh.....

GB meth kit??!?!?! If so I'm down!

[loki]

GB meth kit??!?!?! If so I'm down!

you know me...it can be arranged!!

hahaha

but not just yet...my wallet needs a break. and my wie needs to get distracted cuz right now she's focussed on all my mod spending. =)
