knock, knock who's going to tune my s2 for me?

Hi Shane, I used Martin Tracy in Enfield to Dyno the coupe shortly after getting it.
Not that I would know, but he seams to know his stuff. His is based in the Industrial Estate on the Trim Road in Enfield.

I use a AEM wideband, their not massively expensive but are known to be very good.

do I need one of those guages in the car or will the ecu interpret the output.

Didn't know you dyno'd her, what sort of figures did you get back? How the mfts?

If your using a stock ecu I don't think there is a input for it.

Most aftermarket widebands the AEM included come with a gauge so you can simply monitor it from there.

Its definitely something worth having in a turbo car.

The shopping list grows.. at least I know in time to get the bung into the downpipe before the cats.

Speak to Paul if he is mapping it, I am sure he can offer you the info you need.

You can spend a fortune on gauges to monitor things but a wideband and maybe a EGT probe gives enough info to keep things safe IMO.

Hi Shane,
got 240bhp on Martin's Dyno! He thought a stronger wastegate spring might be giving higher than expected result? MFTS is knackered, I just left #4 terminal unplugged, so no more Autocheck beep on start up! Will get round to replacing it sometime soon. Temp gauge is fine and showing normal temps! Got the dreaded 53 code on the autocheck screen after re-fitting the clocks, but figured it out and sorted, left side knob was pushing against the button for setting max speed warning/autocheck sequence at rear of clocks!

I suspected the dyno is a little optimistic so thats probably spot on for a stock motor. My 7A made 174bhp which seemed a little too healthy for an engine thats clocked up over 300k, even with a rebuilt cyl head.

That'd be the plan anyway, that's useful information re the EGT and AFR guage, zeitronix have a nice digital display that will display boost and IAT later if needed. There's also a vems setup on ebay uk at the moment I might place a bid on.

Interesting to know those figures for reference. Must ask Paul what sort of runway is needed for road mapping.

dont worry so much about the RS2 specs

take all your engine working PERFECT and then give him full boost

knock sensors should be new,the same as the ignition parts

good luck friend

**Rocco** · 23 November 2010, 20:51

ah¡¡ and buy a wideband with gauge YES

i am using since 2 years ago a wideband from Innovatec motorsport...and all it is perfect¡

i am seeing 11.3AFR with 2.1 boost in 5th gear

**prj** · 23 November 2010, 20:53

AEM wideband sucks.
Serial port, weird cable, no RPM/EGT/MAP input.
It's just a fancy gadget, which is totally useless for tuning.

Will check that out too, I would prefer one display to show boost, EGT, AFR and maybe IAT or something at the same time rather than the inside of the car looking like it parked in the pimp my ride / jap scrap / starship enterprise garage for a few days.

Thanks for the help folks

Well, it only shows boost up to 1.5 bar (and that is if you install the MAP sensor).
I did it differently. The display is used for AFR/EGT, and for logging boost I just spliced the wire going into the trip computer (blue-yellow) at the back of the instrument cluster and stuck it into one of it's analog inputs.

That way I don't see boost on a gauge, but I can log it or see it in real time on my notebook.
For looking at boost, it might be a good idea to get a separate gauge. This can be done discretely though.

I will take a picture of my setup.
