g/s stg 1 revo?

[Tucker157]

hey guys, im wondering if anyone could tell me what figures theyre gettin when logging block 002? and what i should be seeing on a stg1 revo, with a pipercross viper ind, ?

i only seem to be getting 80/ 90 g/s flow peak, which is very low isnt it?

am i right in thinking that g/s *1.331 = bhp? roughly? because if it does then im only gettin 120 bhp!!!! feel free to tell me im being stupid and have miss understood something ive read lol

cheers
Paul.

 

[Big_daddy]

Yes thats very low, maf is suspect but check pipes also.....

 

[Tucker157]

what pipes? lol and how much is a maf? can i motor factor it? or is it a stealers only part?

what should i be expecting? about 140g/s?

cheers for the rapid reply

 

[Big_daddy]

Intercooler pipes & vacum leaks, have you logged boost as well?
Maf can be baught from GSF, eurocarparts for aroun £80 exchange or main dealers too, ensure is genuine bosch.
yeh high 140

yeh the req vs acc, is here

is this close enough? or is the difference too much?

 

[James.Judd.1]

That looks spot on to me mate, you wont get much closer than that

 

[Tucker157]

so it looks like a dodgy maf causeing me issues? it has no power between 3k and 4k but has full boost...

 

[James.Judd.1]

Yeah its deffinately a fueling problem rather than boost, so yes maf would be the 1st thing I would change.

 

[Big_daddy]

Do you have full block, for 118 or 115?

 

[Tucker157]

excellent thanks to you all!! its been bugging me for ages, ill need to wait for pay day now.... if changing the maf fixes nowt, what is the next port of call?

 

[Tucker157]

Do you have full block, for 118 or 115?

any comments? is it normal for load to be like that, is a tb clean/ alignment on the cards?

 

[Big_daddy]

Hmmm seems ok but not much of boost spike, do other block to check waste gate duty,

but very certain maf is gone for them boost reading to create only a mx of 90 m/s

 

[ibizacupra]

stage 1 g/s should be more like 150g/s-170g/s, 120g/s is std 156bhp car as a guide

deffo goosed the one you have in it..
clear fault codes and adaptions when you have fitted so it learns its new fueling again..

 

[cuprawill]

i was getting around 160 iirc on revo stg 1

 

[Tucker157]

thanks for the help guys,

will get one on it as soon as i have cash, do i just reset the fault codes on 01 engine? or is there another thing to reset the adaptions?

how is the wastegate duty cycle checked on block 118? the load value?

cheers
paul

 

[ibizacupra]

yes, % figure is the duty cycle in 118, along with inlet temps and actual boost

 

[Tucker157]

what is expected values for the w/g DC? n ill check it out after my work.

 

[Herr.Barbi]

I have the same problem i am getting max 87 g/s ?? I have checked pipes ther are OK is the MAF or what?
But the car seems to Go good! My time on 402m drag was 15,4 without Slicks is this OK or?
I will do a log of block 118 and 115 later and put it hear if somone can help me pleas...

 

[PhilW]

Maf is dead. Anything below 140 on a mapped car needs replacing imo.

 

[Herr.Barbi]

Its a stock engine it sould be something about 120g/s i think or am i wrong? I have a MAF from a leon 20VT 132KW is it the same or??? can i put this maf on my car??
