Rqiew on MB ver 2:

DW - you should really stay close to what you are requesting because N75 map works off drivers wish so rquesting unreal figures isnt really good, it can stay stock untill 1995rpm in last collumn
Torque Limiter - too agressive for clutch from low rpm (18% increase right from 1750rpm!!!) , next I wouldnt really play around with low atmospheric figures if you dont live at high altitude or atleast if you do follow original difference ratio...also with this popcorn limiter you are allowing over 60mg fuel until 4600rpm
smoke limiters - i didnt bother to check damos to found out which one is active but you have changed maf and maps so I'll comment changes)
MAF smoke limiter(if active) - half of your changes in lower RPM are limited by main torque limiter(even in stock) so no point in changing...also after checking rest of file duration map decalibrated so AFR not correct
Smoke by MAP(if active) - only allowing 58mg of fuel which is not even 350 nm and you are requesting everywhere almost 390nm...so no point in this at all...also after checking rest of file duration map decalibrated so AFR not correct
Lambda maps (if active) - also after checking rest of file duration map decalibrated so AFR not correct
Torque to IQ map - only scaledto 380 and you are requesting over from 2000-3500... also NM to IQ maps are decalibrated so 260 nm is not 270nm anymore but higher and so on upto 380...so everything is decalibrated(bad way of tuning)
Decalibrated Duration maps - from 35mg and 1500rpm so now 35mg fual is not 35mg fuel but more which means MAP, MAf , Lambda Maps for example AFR 17 is not AFR 17 but lower so every other map is decalibrated which is completely wrong way of tuning
Turbo limiter by athmospheric pressure - all flat at 2400mbar even at low prssure which is recepiet for dissaster if you go to mountains for example or live at high altitude your turbo will overrev and damage it self and (possible) engine too...

I would actually pass on this tune for free...

also- n75 maps INCREASED !!!!!!! with this much more fuel (and pressure) you are most likely gonna be overboosting so n75 map shoulbe be DECREASED !!!

Wanted a decent performance increase but also to give better fuel mpg also.

With EGR deleted & popcorn limiter :)

Decalibrating duration map is not a way to decrease consumption its just tricking ecu into showing less consumption on display because ecu think for example 50mg are beeing injected but in reality 60 is injected so calculations are wrong, so your consumption is increased/worse but displayed wrong.
Also no sign of egr off in tune.

Thank you for a review my friend. Did you have chance to check the ASX maps at all?
You seem to be a guru on this stuff and I’d actually noticed every time I wrote the map that my fuel in range and gauge would stay on 0 until I put more in!

Would you be the guy to help me with a good map at all? I’m happy to pay for quality.

Do you want to learn or just want the remap?

About ASX file
torque limiter increase from 500rpm, at those rpm car is at idle and it doesnt need more power lol
MAF smoke limiter - allowing AFR under 14 in 850 mg MAF (again alot of smoke and unburnt fuel, also high exhaust temperature
Boost map - 2.3 bar for this turbo is too much , 2.2 is maximum and this much boost will shorten it's life significantly
n75 stock

Thanks for that info mate. I’m glad I haven’t bought one in this case. Was just after the remap really as I use a MacBook Pro and just use windows in a virtual environment to write / read the ecu so I don’t think it’s something I’d be doing often in all fairness.

Is there also some sort of software that will read the remapped file to show a simulation of it on a dyno at all or to show you power increases / torque / fuel consumptions as I seen some have but unsure if on a computer or actual dyno lol.

Ah I see. Let me know if you can help at all :)

Did a long drive today (200 Miles) - put £30 in and got about 270 Miles out of it. Not good however your descriptions above would make sense of it
