Custom map lots of mods stuck at 170bhp

[sepulchrave]

....he sent me away Saturday with possible tandem not sending enough diesel so will check this tommoro at a deisel specialist how plausible does this sound to people who know about these engines more? Also on his website he quotes 193 bhp - 309 ftlbs of torque on stock everything

The problem is not with the fuelling but the air, not a chance of 193bhp with everything stock, what you have now is what you get with everything stock. What hybrid turbo do you actually have fitted?

[Jonny5ive]

That sounds a bit high for stock

That sounds a bit of an understatement!!

[Georgevrs]

Stage 2 hybrid can't remember all the numbers gt17 high flow compressor wheel enlarged exhaust side by 4.2mm uprated pad, I think that's most of it I can dig out paperwork if you need exact numbers

[D15VRS]

Ditch Celtic tuning. Any decent mapper will tell you the 190 bhp is not realistically achievable on stock components alone, and that a smic would be enough??? If they also supplied the hybrid I would be doing some digging on this as well.

Hope you get it sorted.

[faboka vrs]

If you have VCDS lite log the following from 2k to 4.5k.

Group 3 - MAF values

Group 11 - turbo pressure values

Group 8 - fueling requests

Group 4 - actual fueling and timing.

Log each one seperate to give the best sample rate and post up the log files or PM me.

BLT run the smoke map based on the MAP sensor not the MAF. Well all the ones I've seen do.

[Guest BigJase88]

Also cat wont be restricting!

Stock exhaust is capable of in excess of 220bhp!

Basically ditch the mapper as he has about as much idea as no idea

In my mind a fmic is advisable at even remapped power! I could put my old fabia vrs into limp mode with 173bhp if i tried hard enough! Was heat soaked after one blast up through the gears

[DanGum]

bloke sounds as much use as tits on a fish

 

go to any of the forum sponsers on here, all have decent reviews, they'll sort you out

[tommccabevRS]

Mines at 177bhp 300ftLb's and that's pretty much maxed, so where he's getting 193 bhp from I will never know.

[RAPTURE]

Send ya map and logs to Faboka, he will work his magic on it .  www.hidden-power.co.uk

[Georgevrs]

Just doing the logging now faboka thought it may be worth mentioning when my car was standard it only pulled 129 bhp and about 210 ft lbs

[Gobsheene]

AFAIK RevoTechnik will give you a "try before you buy" session and will map your car taking into account your mods and adjusting the map accordingly.

Thanks gobsheene but when I was doing my research about 8 - 10 of my friends went to storm and all of them went somewhere else within 6 months as the maps were terrible but I'm prepared to drive just need to save the pennies now as I def want a fmic before anyone tries to get more so I have made sure that its 100 per cent ready for that power so its all down to the mapper then.

Oh Wow!I know nothing about Storm themselves, only that they appear to be a REVO dealer. 

 

I've a good friend that is a dealer here in N.Ireland [Performance360] and despite me not having a REVO map myself, alot of people rave about them here in N.Ireland despite the extra cost over the competition.

 

Might be worth an enquiry as some people will sell their own maps and a branded one also.

That figure seems low for a BLT, is there an underlying mechanical problem, compression, cam timing or top end wear perhaps?

[Georgevrs]

He did say that was the lowest he had ever seen i might get it compression tested it needs a new rocker cover gasket so would you be able to see camshaft wear when that's being repaired? It is also due for a new cambelt in next 5k but if timing was out would it not run weird and wouldn't it throw up error codes that the mapper should notice he runs full diagnostics before and after.

Fault with the MAF sensor. Stock turbo should see around 1100mg at peak torque dropping to high 900s at 4krpm.

But BLTs run of the MAP sensor anyway. Will let you know more when I see the rest of the logs.

[faboka vrs]

Just realised. Are you just revving it when stationary? Really need 3rd gear pulls.

[Georgevrs]

Just emailed over ones whilst in 3rd gear bud

[faboka vrs]

Received the logs. Will take a look and post up my opinion.

[faboka vrs]

Turbo pressure. Remember this includes atmosphere pressure.

Here we can see requested from the ECU is only 1.5bar with actual struggling to meet requested up until 2500rpm. The below N75 duty cycle shows the ECU entering open loop to try and gain control of the boost.

 

[faboka vrs]

MAF reading. This shows how much air is passing past the MAF sensor. I would expect more airflow from a hybrid but at the same time it is only boosting 1.5bar. A hybrid should easily hit the 1249 diagnostic limit. Josh if your reading your old Ibiza achieved this when running around 1.8bar on the original PD130 mapping and your PD130 hybrid.

 

[Guest BigJase88]

Requested boost should be 1.8 bar on a stage 2 pd150!

Looks like a generic map to me!

Sack the mapper

My pd150 STOCK turbo is running at 1.6 bar

[faboka vrs]

Fueling request.

 

Background. Are ECU decide what fueling to inject based in 3 maps. 1st is the drivers wish (go pedal), 2nd is the torque limiter and 3rd is the smoke map. ASZ smoke maps are based on airflow past the MAF sensor, the BLT is based on the MAP sensor so turbo pressure.

 

Here we can see that both the DW and TL at flat lining at 70mg/str (diagnostic output limit, probably requesting more). With the smoke map flat lining at 60mg/str. This confirms to me that the ECU is in fact running on a smoke based on MAP sensor map as the stock file is limited to 60mg/str. An ASZ file doesn't have fixed values across the rev range.

 

So out of the 3 maps the smoke map wins as its the smallest.

 

[faboka vrs]

My pd150 STOCK turbo is running at 1.6 bar

 

Stock PD130 is 1.35bar,  PD150 is 1.5 bar, PD160 is 1.55bar
