My 1st Log (not yet potty trained)

[johnboy98]

Hi peeps well collected my LCR (210) 2 weeks ago now and apart from a few neglected areas by the pair of half brainers who used to own it, ive gotta say im more than chuffed with it

I seem to have a spuradic problem with the throttle every now and then the engine will give a fairly violent jerk when on low demands and also high demands and this jerk is even more prevelant when you throtlle off fairly quickly.

Rather than do the usual annoying nooby stuff of just asking questions without putting in some effort my end ive taken it out with vagcom attached and logged a few results, this is the 1st turbo'd car i have ever owned and am pretty new to working my way around Vadgecom aswell so go easy on me.

only mods on the car AFAIK are Forge DV007p and a Miltek exhuast...dont know if its been mapped yet as I want it to run sweet before a rollong road sesh!!

Thanks in advance.

Your air mass meter looks low for 210bhp. The max i could see is 121.8
A 210BHp x 0.76 = 159.6 g/s

Not enough revs....

what it needed is 4th gear 2000rpm wide open throttle (all the way, no lifting) to high revs.

 

[johnboy98]

Yeah i thought the airflow looked low Big lad, I will take out and do as you suggested Mork and thanks for the speedy replies

 

[Big_daddy]

I would personally do it 3rd gear as 4th gear seem to never end at high sppeds. From 2rpm to 6/6.5rpm

You may want also try these blocks (2 ata time)

003 + 020
115 + 031
118 + 032

 

[m0rk]

3rd won't have enough load, especially on an LCR.

 

[Big_daddy]

3rd won't have enough load, especially on an LCR.

Oh 4th would then be ideal then, as i never logged a lcr before

 

[johnboy98]

OK just braved the great blighty down pour, heres a set from 2000rpm in 4th gear upto 6000rpm.

the airflow in my limited opinion looks rubbish MAF clean or replace, the car has done 47k and im making roughly 19psi is that about right any thoughts dudes?

it's not really long enough on a remapped ibiza since you'll buzz through 3rd too quickly

Does your car rev easly on full trottle? all the way to the redline

 

[johnboy98]

arh not so good, so i need to sort out my vagcom/user interface problem before I can fix the car.....

 

[johnboy98]

Does your car rev easly on full trottle? all the way to the redline

sometimes yes and sometimes no the odd hiccup here and there and I got it to backfire today after dropping the load off quick.

 

[Big_daddy]

You may want to log the cylinders counts for misfire.
Just for the air mass, try this full trottle in 2nd 3rd and 4th, im not 100% convinced.
