so if I buy a chipped ECU or chip my own, then I can just download a basemap that fit's my application and that's it right? Or do I still have to do some tuning?
I just came across this page: http://www.-------------/chipping-kit...cus-p-277.html

If I get this and get them to do a basemap for me, would that work? thanks

 

still will need tuning.. what you are downloading is a just a rough estimate of what your car needs

 

The car will run nicely (usually) on the basemap provided and can be set to suit your set-up aproximately but no two builds are exactly the same therefore some tuning will need to be done. I have just started to tune mine via a wideband O2, a datalogging cable and a moates ostrich. the map I got with the ECU from xenocron runs the car fine but it is a bit rich. I'm using the free datalogging program called Freelog and i'm using Crome free to play with the maps through a laptop. The Moates Ostrich does away with the need for a chip burner and chip and has the advantage of being able to upload map changes on the fly so you can hear and feel the changes as they happen.
You need to be able to analyse the exhaust gases to tune properly hence the wideband O2 sensor, unless you have access to lots of dyno time (who would have gas testing equipment). These are the forgotten costs of turbocharging but if you're willing to have a stab at it then you'll save lots of money in the long run and will have a much better tuned car than you could get just sitting on the dyno, as dyno tunes can never properly simulate real road conditions.
The ideal stoichiometric value for petrol cars is 14.7 and this can be acheived throughout the fuel table by tuning the ECU at home, just think how much fuel you'd waste with an FMU at 12.1.
Good luck

 

Ok, that's what i'll do, but until I get some extra cash, just to clarify the car should run fine with the basemap they give me. and with this setup I should be able to get around 8 PSI safely? thanks

 

yeah if the basemap matchs your setup it will be fine but I wouldn't go nuts and bring it to a track or beat on it untill its tuned

 

yeah, I'll take it easy on it, besides I don't really have any plans to do any racing anyway, I just wanted to have a car that you don't have to have it to the rug to hold your speed with 4 people in the car, lol.
anyway, thanks for all the help, much appreciated.

 

Yep, it's what I did and had no issues other than it being a bit rich, but being rich is safer than going lean. I'm running a shade over 9psi on stock everything. I think though that with 8psi you'll be looking at a good deal more than your 170bhp target. more like a realistic 200+
