Hi guys - that mongoletsi chip is out - was at ATS again and could not get it to work propahly, as you can remember from way back I told you about the mongoletsi remap bla bla bla...

Dastek on a N/A 2.0 16v???

Aparently they can alter according to the needs of the driver, with this mongoletsi Pino could not...coz #1 he used diesel parameters and #2 it was for cars in Europe so all the guidelines were based on European conditions bla bla bla(don't want to go deep into that issue as its still disputed:twisted:)

Ok...on Sat I'm going to a Dyno again, not ATC's, and put the car on there...what I'm expecting is MUCH more increase in tourgue...if you can remembah, last time I thought the clutch went coz of this mongoletsi remap but was not the case...ATC's dyno overeads inputs and then gives you a balooned figure...so can't be true! Im at 180Nm standard, and even the Polow's have more Nm's than that...maybe over 200 and I'll be heppie I don't want increase in powah - just more torque from 1500rpm to 3000rpm...coz right there the car is a Yaris T1...oh, getting the K&N panel filter installed before the Dyno with a normal ECU reset and trash on highway so that it can calibrate the AFM with the new addition - also doing cambelt service and changing variator on same day which will bring engine back to factory performance as variator killed performance noticably!

Do any of you guru's think a Dastek will be worth it? Already free flow custom exhaust and now panel filter with some airbox mod to increase airflow...didn't take cats out yet...waiting a bit with that...

I know Ford Fiesta ST's with a dastek is hectic for an N/A car...at the tolls to JHB was chasing one...from 1st we sat it hit 2cnd then I saw the dasktek sticker...it pulled like a N/A car but I'm sure it would have killed a standard 147kw GTi for sure...it killed me from 2cnd and the gap was about 10m between his tailpipe and my front numberplate...yoh... if I can get torque up I would be heppie!

opinions pls!:p
 
You are not going to get much more out of a car that does not have turbo. All these chips, including the dastek, work fantastically in turbo'd cars. I put a dastek (Unichip) into my Nissan Sentra to try sort out a fuel consumption problem. Well it cost me 3.8k and so far has done nothing for my fuel consumption. It only gave me a couple of extra kw and about 10nm torque (the chip was set for fuel economy, not performance). My throttle response is better and my torque curve is more linear, so acceleration is better. But thats about it... Other than the fact that my car no longer dies when coming to a stop (used to drop to low in idle), the chip has been disappointing. BTW I went for the cheaper option on the chip. They set it for you and then it stays at that setting. The more expenxive option will let you change settings via your mobile.
 
Oh cool, is it a STi? Those things are quick, I'd say it can eat a Fiesta ST? but I've seen Vtec's KILL Fiesta ST's like crazy. If the torque curve can be linear I'll be happy...Nah, I won't want to change the setings
 
The chip on it's own can only optimize on the factory's "general" settings. So if your car was one that was within parameters a chip only won't do much. BUT if you change the amount of mixture coming in and that what leaves i.e headwork/exhaust/turbo etc...then you win by chipping as you now can optimize for the mods....the reason for chip tuning. Why it works well on turbo cars is that it takes away the factory's margin built in margin for optimum longevity. You win handsomely in performance, but you chuck your longevity if the tuner does not do a good job. I would not trust any person plugging in a chip in my car without tuning it on a rolling road...it's kinda defeating the object........
 
adding...if the Mangoletsi chip is tuneable...which I can't think it is not...by plugging in a computer and setting the parameters as the car is sitting on the dyno, and your tuner did not do this, but just chose from available pre-mapped settings....then you will get the same deal from the Dastek. The guy plugging in the Dastek will choose a map and send you off, so you will be back where you started. If you are lucky it works better if not it will be worse.

Sooo...if the Mangoletsi chip can have it's parameters set manually, get someone with a dyno and a computer and the knowledge to use both to tune your existing chip. If not get the same type of person to tune your Dastek...it will be a bit more expensive than the "plug n Go" guy...but you will get the full benefit of your mods.

just my dos pesos....
 
My Unichip was set via laptop while on the dyno, took about 45 minutes to set all the fuel/air mixtures at the various revs speeds. The guy at SAC's in Durban used to work for Dastek.
