Had my Leon FR PD150 revo remapped today.....not as good as expected :( NOW WITH LOGS

[cleverspoon]

hi there, treated my car to a stage 1 revo today after many debates with myself.

Dyno run before (completely standard) = 152bhp and 250lb-ft
Dyno run after (stage 1 revo) = 175bhp and 257lb-ft

being a saturday the full garage wasnt open and only really do remaps, the guy seems to think there may be a boost leak explaining why im not reaching around 190bhp and why i only managed to get an extra 7lb-ft
however he did a few logs on actual boost and req boost and its meeting the req, i questioned a boost leak and he said it can still leak boost, the turbo is doing extra work to meet demand.

the car does whistle on boost but i understand some whistle is normal.

iv had the joint on the inlet of the intercooler removed cleaned and refitted and modified with cable ties to prevent it comming apart.

my first step i guess is to check for boost leaks, im about to do a search but is there any particular way specific to a pd150? i understand most of the joints are prone to fail, i had a quick look on the joints around the engine and all seem dry, im going to jack up the car and look at the intercooler pipe to check them.

The car does seem a bit quicker, especially 2200rpm to 3500rpm.

thanks in advance, Jack

Boost leak? It's ok producing standard power though, seems to me a leak would reduce standard output too

 

[cleverspoon]

thats why im not 100% its a boost leak, plus its actual boost is meeting the req boost? even if the turbo was weak/ on its way out i wouldnt of thought the actual boost would meet the req boost.

it was a decent vag tuning garage which im sure know what theyre talking about, although he had never heard of silent SMF, im sure southbend and awesome do a silent smf (or almost silent)

 

[Sxanth]

Strictly speaking they aren't silent I have an awesome one. But yeah it's quiet. If it's boosting ok then maybe not enough fuel is being sent. What's he expected result for these?

 

[cleverspoon]

he said i should expect 190bhp....he didnt say about torque, but research says around 290/ 300...i would expect more than 7 that i got. im wondering if its a dodgy map as the car produced a good 152bhp and 250 lb-ft standard, which seems to be good for a 9 year old moter.

 

[jonjay]

Could be loads of different things.

I would get the MAF looked into. If it is not meeting required boost it can still be a boost leak or actuator mot opening and closing the veins on the turbo properly.

Where did you go to get remap? Did they check for boost leaks? Do you have logs? What is your duty cycle readings?

 

[cleverspoon]

i got it mapped at tsr in bridgewater, didnt spend any time in looking for boost leaks, i needed to get somewhere plus i dont think they are fully open for that kind of work on saturdays.

iv been wanting to run some logs for a while, may be a good excuse to do some myself.

he logged actual vs requested and it was all ok, surely if it was a boost leak the actual would be down compared to specified?

iv read a lot about sticky vanes, i regurly give the turbo a good run to help keep vanes clear, the cars only on 60k and has seemed to be ok so far (touch wood)

what should i log to check maff out?#

iv turned the egr valve down on vagcom if this makes any difference.

the only thing that confuses me is that it made good power and torque before the map...surely if there was anything wrong it wouldnt of made 152bhp and 250 lbft?

so im going to log the maff, boost (actual and req), duty cycle (not sure what this is), any others? also what MB numbers are these?

thanks for your help so far Jack

the wooosh/whistle is normal on boost but do your hear a siren noise?

I wouldn't worry too much if you do hear the siren nosie. My pd160 Ibiza has that nosie and stage one mapped with extras and pulls at good 195bhp turbo is still in fine working order

 

[darkhorse]

Make sure you aren't getting any clutch slip as well

 

[cleverspoon]

Im not getting any siren noise from turbo. I dont think the clutch is slipping....im sure the garage would of noticed if i was. Hopefully going to do some logs one night to check maf and boost etc,

 

[cupra.al]

i think people expect a little too much because of the things that have been said on the forum or in my case i did about how good a remapped pd150 is there not as good as they are made out to be after a remap.
yeah you can feel the difference but not like you can on a 20vt.

 

[cleverspoon]

I dont expect a ferrari, but i expected more than 7lb-ft torque.......hopefully some logging will shed light.

 

[N1njaboy]

I had my 1.8T stage 1 mapped at TSR and if I'm honest it wasn't as good as I thought. Bought a revo sps and adjusted the settings myself (seperate datalog sessions for every change), now it pulls VERY well. Not sure what the logging blocks are for a diesel but I wouldn't have thought it was much different to a petrol.

MAF - 002
AIT - 004
Knock Sensor - 020
Boost - 115

 

[LEE69]

Even the revo website says and increase to 190 bhp and 290 lb/ft

 

[Bondiblu]

Log MAF channel 3, log channel 8 (IQ limiters) and 11(turbo) too.

 

[ibizacupra]

PD150/PD130 rarely make just std power, so if it did 150bhp its already down..
I have never seen a PD130/150 make std power as std, always more...

130 often do 140-145bhp std and 150 often do 165-175bhp std

If the 150bhp is indicative of that, then its as much down as you are looking for.

 

[cleverspoon]

Thanks for the info about standard power bill, i have heard they sometimes output more standard......if the actual boost and req boost is the same, could there still be a boost leak? As its giving the boost that is req.

If the maf was on its way out, could it be possible that its ok at idle but is faulty at mid range, which is where im loosing my power, hopefully the logs should answer this.

Another thing im dreading is chocolate cams? If they are on their way out would this loose power midrange? It idles ok and sounds ok when cold, i mean very cold....left sitting for a week when we had frosts.

[cleverspoon]

i dont know how to fully interprit the logs...but the maf seems to be above specified, so i persume maf is ok. also the actual boost meet/ exceeds specified, so im guessing theres no ajor boost loss.

im a bit stumped, anything else to log?
