Mk2 Tiguan Tuning

[jcheung_23]

Who is doing the tuning for this? Are you staying with Spectune or going a different way?

Interested to hear how you go.

I am going to retune on a dyno at tarmac engineering/Spectune. Those guys (Ben) are very experienced at tuning our vehicles

Hi The_Tig, it’s an exciting time with you and J_cheung23 both installing an IS38. I wonder if there are many others creeping the streets with their IS38 sleepers?

It would also be interesting to see whether an aftermarket intercooler (APR, Wagner, Intergrated engineering) does anything for power? In some of the IAT graphs it seems that there could be upto 20 degrees difference with a good aftermarket intercooler vs stock, this would translate into more consistent power delivery. In particular I know J_cheung is Queensland based, so this might be a necessity for the hotter whether to reduce IATs.

Keep us posted on your install tomorrow. Very exciting.

Yeah since I changed the intercooler on my mazda MPS I've noticed a big difference, our summers are 30+ degrees. But the intercooler was an absolute nightmare to install... took more time to do that than installing both downpipe and turbo combined. Since I'd be mainly surprising those HSV/Holden SS at the lights with my Tig (rather than taking it to racetrack), I might not go ahead with intercooler upgrade

Off the line with launch control, the Tig is surprisingly nimble. Going up against stock hsv and ss shouldn’t be a problem with an is38.

If it’s a few squirts here and there you should be ok. I heard the IC for tig should be quite straight forward 2-3 hrs work. People have also changed the throttle body pipe and turbo outlet pipe at the same time. There aren’t many dyno charts available showing before and after gains though and it’s more anecdotal like “better throttle response” or “bum dyno” increase. Has anyone changed these on an MQB platform and is able to comment on their experience ?

Ignoring all the for/against of piggyback vs. flash, has anyone used a JB1 or JB4 on their 162 yet?

Would be interested in hearing any feedback.

The only problem with the JB1 / JB4 is they are limited to effectively a low output stage 1 file. If you ever decide you want some more again then you have to start again with the flash tune route.

Good thing is you can sell them and recover some money when you sell the car. Tunes you do your dough 100%.

The problem is there's not a lot of back to back comparison testing for flash vs. piggyback so it's just a subjective opinions that you'll get. Most people will think that it's great until you get used to it and then you'll want more....

Which is why you really should get a flash that's upgradeable to start with

You would expect the gains to be on par with a Golf GTI.. but you need to work out how the JB4 fools the stock sensors and if it may affect anything else in the car such as the Haldex, etc.

From my tuning background (work with only JDM cars, aftermarket ECUs, reflash EVO ecus, etc.) I hate piggy backs with a passion.

I've got a JB4 on mine, and have been happy with it - by far the better option if you're concerned about warranty etc. They're hugely customisable too so you can tinker away if you're that way inclined. Paired with the bluetooth adapter and iphone app, it's a fantastic way of getting some more power out of the car

JB4s are not like the piggy backs of yester year, it has some smarts and used on a wide range of cars now. BMW, VW, Merc KIA stinger. Good little unit for the price. Enjoy mate

What are the claimed power outputs compared to APR etc. stage 1?

What are the claimed power outputs compared to APR etc. stage 1?

Hard to say mate as APR use flywheel numbers...
APR say 87hp, so ~65kW, then minus what you think drive line loss is

I got ~25 Wheel kW gain from a pre set map 2 (which is +5psi over stock)
Only mods were the airbox cut out and foam high flow filter.
You would be able to make Map6 (full custom) with a stock car and make more than 25kW (easy)
- a Mate got 50kw and 100nm gains with map06 on stock GTI PP

Note: FWD only (GTI), 169kW at fly, 153Wheel kw
Stock, Map 1 (+4psi over stock), Map 2 (+5.xx psi over stock)

Im currently Over 200 Wheel kW with intake and downpipe, Once I do an Intercooler, Ill prob go see Ben at BSP/tarmac engineering/Spectune. Mate has over 235Wheel kW with there tune.
