SPS 3 Settings

[jambojones10]

Just got myself a SPS 3 switch for my Revo'ed beeza. I'm not that technical so unsure what settings to try. My spec is: N75J, Forge 007, Dynatwist. Always run it on Optimax or Ultimate. What settings does everyone else use and what settings should i try on mine? Cheers

 

[Daz_gibbo]

I run timing 6 and always run on Optimax. Boost is usually set at high boost 6 or 7.
The best way to determine what settings are best for your own car is to get VAGCOM on the job and do some logging. Start with both low timing and boost settings and take some logs. Then alter the settings and log again. Stop when you recognise any timing retard within your logs.

and put the original N75 Valve back in.

timing 6 boost 6, tried boost 7 and as i have a std intercooler, the ECU backed it off.

 

[r1cky]

is an sps3 worth getting? i have revo but never tried an sps. or would other mods such as downpipe and cat be more benifical?

 

[flashbsd]

i would say to you, go stage 2 for the money, you have FMIC and stage 1 already, only 49 quid!

Downpipe is a good mod apparently though, or a K03s

SPS3 is only if you want to tweak settings that the dealer preset, if you told them you use optimax youll be on 6/6 already, if not timing 5 for 95 ron and 6 boost.

not worth the money IMO

 

[Daz_gibbo]

Worth getting if you can pick one up for £170

do you have some logs of hb6/7 settings (especially blocks 115/118) ?

 

[Daz_gibbo]

Nope, I could get some though. I will have to steel my missus USB stick too.

in fact i've sorted some of my problems (maf was sick i now have 160+g/s) and i'm interested in stage 2 , i would be happy to see some logs

Boost 4

Timing 5 or to suit petrol grade.

Theses are Stage 2 settings but I found Stage 1 to be similar if not higher.

I have a nice Excel file showing why I run the boost so "low" but I can't post attachments.

This is a CSV file of B9 T3 (T3 to avoid any chance of det/timing pull for this experiment):

As you can see, after 5K RPM the N75 is 100% duty cycle - the turbo is flat out. So I dropped the boost until the req vs actual were in line after 5K RPM - this was best at B4. All that happens by setting the boost higher is that the low RPM boost spike gets bigger but the peak output power of the car stays roughly the same.

do you have a N75J ? the boost spike is high regarding to the requested, and until 5000rpm the delivered is really higher than requested

It's the stock N75 that it left the factory with - these are both 3rd gear runs, the spike isn't quite as aggressive in 4th but finding a bit of road to hold 6K+RPM in 4th is a bit tricky.

The 3" DP, sports cat & 2.5" cat-back most likely exacerbate the overshoot - IMO the boost control / request needs to be softened / smoothed out a touch at low RPM for better driveability but that's up to Revo.

ok

knowing you have at least 3" DP, sports cat & 2.5"cat-back, revo stage 2 (i think a fmic seeing the temperature) i would say the mass flow numbers are a bit low , no ?

here is glenn excel file : here

Possibly, but it's a stock airbox with paper filter and the characteristic is exactly as it should be with that boost curve - i.e levelled out airmass, boost drops off ~linearly with RPM.

I didn't get Stage 2 for more power, I did it because I didn't like the high injector duty I was seeing on Stage 1. The only difference I could tell on the road between Stage 1 & 2 is that 2 is a bit smoother - mass flow was the same, car isn't noticeably quicker. While I was experimenting with high loading (low RPM, WOT in 5th gear), I found the clutch would slip on Stage 1, it doesn't (ever) on Stage 2.
