vagcom readings can someone look please!!!

[jay-cupra]

hi all i had my ibiza hooked into vag com tuesday evening and was very shocked at the out come!!!!, it is saying i am getting actual boost of 2.5 bar when the requested is 2 bar and my maf was reading as high as 188 which if you times that by 1.2 you get your rough bhp which i work out to be 225bhp. But its on a k03 turbo and they can flow enough air for 225bhp,

a brief spike above 1.5bar at 3krpm then 1.2-1.0bar to 5krpm

 

[jay-cupra]

I take it's fine running that pressure on k03, I thought with it reading 2530 mbar at 3360rpm it was boosting to 2.5 bar but I don't really know what I'm looking at, is 188 MAF reading good flow for a k03??

 

[jay-cupra]

oh I forgot to say thanks for looking bill I valve your views

 

[Big_daddy]

188 m/s is REALLY good espically for a ko3, more of k03s terrioty

 

[aaron-gardner]

What I's the best way to calculate bhp from maf readings. Some say it's g/s divide by 0.8 and this thread says multiply by 1.2. Basically 188g/s can be either 225bhp or 235bhp

I have a stock mapped auq with 180bhp (approximate) with only a cold air intake with open cone and Decat exhaust and I'm getting 141g/s which I's either 170bhp approx or 177bhp I know results are close but what I's the best method?

 

[Big_daddy]

Ive always used 1.3 but at end of the day its just a estimate.....

 

[jay-cupra]

Ye I thought 188 from a k03 was good, guess my Jetex is doing its job , it's defo a k03 cos it's flat after 5500rpm and runs out of puff, but it is a torque monster

 

[tstrahonja]

188 seem too much for k03?
I have never seen anyone's post reading so much g/s on k03...
Can broken MAF overread instead underread?

 

[jay-cupra]

I'm pretty sure MAF is fine runs spot on to be honest, Im 99% sure it's still the original turbo from new and its done 140,000 miles now, the guy who I brought it off has every receipt from new and there isn't a receipt for a turbo at all!!!

 

[aaron-gardner]

Well if your reading 188 then I wouldn't complain but it I's high readings from a ko3. Just hope it's not being pushes too hard but if it's going strong at 140k it should be ok. I have been using dash command and my g/s reading I's 145g/s and bhp I's 181bhp which works out 145 divided by 0.8 so I would say that's a slightly more accurate way of estimating power. However there are other factors such as timing which may alter the figures.

 

[jay-cupra]

Ye I know I was expecting reading around 170 but 188 that's just mad and it's at 3300rpm so as you can guess its a torquey engine

 

[miller 666]

Just like to confirm this car is an absolute weapon!
No shadow of a doubt that's it's underperforming at all

 

[jay-cupra]

miller I take it you mean you have no shadow of a doubt it's NOT underperforming haha

1. Boost pressure read by VAG-COM is an absolute value. That is, if it reads 2.53 bar, you have 1.53 bar over standard atmospheric pressure (which doesn't take into account the fact atmospheric pressure during that specific day migh have been a bit higher or lower than exactly 1 bar...)

2. To get flywheel bhp from MAF reading, multiply the g/s with 1.25. RobDon found out by trial and error the resulting value is almost spot on (to the accuracy of 0.1hp) the flywheel hp read by a dyno.

3. Maximum bhp is just as hard to get on road as best 0-60mph time is. During a motorway trial 1 month ago, while running 180-200 km/h and accelerating from roughly 140 km/h, best MAF readings were only above 150 g/s and most of the time they stood in the 140 g/s range, while a dyno-proven 230bhp car should have gotten 184 g/s.

But to get peak hp and therefore g/s throughout rpm range, maximum boost and WOT have to be run continuously in each gear, from start to redline, like it's done in a dyno test. Just like when doing a 0-60 test, launch has to be perfect, boost at the max, throttle control perfect.

In practice, we do not try so hard our engines on the road, maybe a few times in the entire life of the car. But the modded 1.8Ts are so ridiculously overpowered in comparison to the weight of the car, that even mid-range hp feels like peak hp in lesser vehicles
