Hi,

Just bought a 12 plate S3 Sportback.

I've had my suspicions that the cars been mapped, so I ordered one of the Racelogic liquid gauges,

I've just been out in the car to see and sure enough it has, things is its running approx 345bhp peak and torque was peak at 340lb ft and trailing off to 300-320 as the speed increased.

I was under the impression stage 1 would be about 300 ish bhp and similiar torque.
I can't see any other supporting mods, I haven't even had the engine cover off yet,

What power are others running on stage 1 ?
It's quite nice that it's mapped as long as it's a good safe map, problem is I now don't know whose mapped it.

Do you think it's worth me taking it too R-tech etc to get the car checked over ??

Cheers
 
I got them figures without any mods from unicorn

Cool...

What plate is your car Joe and has your car been reliable with that power ?

Have you not updated your fuel pump ?

I'm still new to this engine so not sure what is fact and fiction with regards to tuning
 
Do you know how accurate the gauge is as those figures are high for a stage 1 map?
My S3 did 327 bhp + 342 ft lbs on an APR stage 1+. This needed a high pressure fuel pump but I was still running the standard air box.
You may need someone with diagnostic specialist knowledge such as R -Tech who can decode the settings for you and tell you what stage is really running at with your hardware. If the fuel pump internals have been uprated you cannot tell by looking at the pump unless it is stamped with Loba, APR etc.
 
I'm pretty confident with the liquid gauge, I had one with my S3 8L, it just plugs into the obd port and reads what the ecu is seeing / slash requesting.

I know the boost is requesting about 1.4bar, I spoke to R-tech earlier but they are over 3 hours away.

Think I'm going to go and see "Quattro Tech" in St Ives who are suppose to be good, I'm considering putting Revo software on the car so that I at least know which map I'm running and is set up correctly,

Anybody had any dealings with Quattro Tech, and anybody running Revo stage 1 ??

Cheers
 
mine is 2010 one. yer its been spot on to be honest

I ran Revo software for some years and was quite happy with it,but the current feeling from many of us is that they have kind of left the 8P engine and moved over to the 8V.

Rick @ Unicorn is one of the current leaders in 8P tuning.

Yeah I spoke to Rick too, nice bloke !

I'm not too worried if Revo have stopped evolving their stage 1 map for the 8p, so long as it is a good reliable map they finished with.
I'm not looking to go any further than stage 1,

I couldn't fault Revo on my old 8L S3 !

It's good and reliable enough in terms of engine mechanicals but not the best in terms of performance or added features.

Thats good to hear, 300-310bhp I'd be happy with !

Saying that, whatever map I'm running now feels lovely, very quick ! Shame I don't know who did it...

I think you still need to investigate whether the fuel pump has been updated to get those figures. Also if it has an updated pump it wears the fuel pump cam follower more quickly and so you need to get that checked. If it wears through, you will have a very big bill

Is it easy to tell if the pump has been changed ? I thought about popping down to Audi tomorrow so they could have a look.

I'm going to get the follower changed as soon as the car goes in, if I pop up to Quattro Tech next week I'll get them to change that at the same time.
 
Essentially, the outside of all the fuel pumps look the same so Audi could not tell by looking at the pump on the top of your cylinder head. You may be lucky and have an APR or a Loba stamp on the outside. However, I have a Loba pump with no external stamp so it looks exactly the same as my original. It is the inside components that differ. The cheapest way is to fit Autotech internals to the original pump and so you need an expert to identify the modified parts after the pump is taken off.
Yes get peace of mind by changing that cam follower.

Shark did mine to Stage 1 and mapped my DSG too. I have a graph somewhere put to me it pulls like a train. I went too far with my Subaru with poor mods but this S3 is in a league of its own. I mean, more power and DSG! Wow! LOL. Incredible.
And please don't fill up with sh1t fuel like a lot of 'boys' do.

Shark also done mine but can't enjoy fully as too much torque for the clutch straight away so saving to have it upgraded then can test properly.
 
Not sure, but I know the liquid gauge uses maf readings to work out bhp etc, so I'm assuming the maf would have been about 276 g/s

I've since had the car checked out and on a dyno because I didn't like the fact I didn't know who had mapped the car in the past and why the readings seemed so high,

On the dyno the car ran 304bhp and 313 lbft but was over boosting and the torque was coming in in a lump and dropping off quickly, the graph was not very nice, the tuner wasn't sure if the map was causing overboost or the car was at fault.

So the plan was to load the car with a stock Audi map to see how the car performed, this was done and the car performed perfectly, so then a Revo map was put on the car, the graph looked just like stock but obviously higher power everywhere, very happy with the results !

Car made 309bhp and just under 300ft lb, torque could have been raised with more boost but I was told the car seemed really happy and cool running these figures.

Not sure why the liquid gauge differed so much from the dyno runs, can only assume it was to do with the overboost.

I had Revo on my previous S3 8L without any problems which is why I went this way again.

The obd port measurements for boost are not actually boost pressures. They are calculated via the maf and temperature changes : not accurate
 
Actual boost will be predicted via the maf etc but the requested boost is accurate as it's read from the ecu.
