VW Caddy 2.0 SDI 70HP tuning

[Fec001]

Hello!
Did anyone make a tuning for this SDI before? If anyone yes, please write i'll pm to him I need some info about this

[Fec001]

Is this file original?
Car can provide 140Nm originally but in TL map values are higher than 220

[ludbe]

i can make

[Fec001]

I'm sure you can make :)

[morgano]

If non turbo then your limit must be at smoke limiter, not internal engine torque.


Regards,

[Fec001]

There is no MAF smoke limiter in this dump, lambda is the key. It was explained by helpful member ludbe. All clean now!! Thank you!!

[morgano]

Well, lambda in fact is smoke limiter on diesel cars :)

[Fec001]

you are right, function is the same so we can call it as smoke limiter if you want :).

[morgano]

Now push it to see how much you can gain without looking like a squid :)

@Fec001-SDI-Saugmotor(aspirated engine)-how much additional air can enter to the engine-0 mg air-how much extra power can get?in the best case max 5-7HP, but probably with some black smoke on exhaust.I don't think it's worth the effort.

[ominimicu]

Nastase is RIGHT.
i ve done quite several of those...and no way to get it right..maybe just a bit of better fuel economy.
problem is cant maintain AFR ratio...becasue of no extra air

My suggestion is to start by logging relevant parameters, then from the logs you can see where you may be able to make small tweaks. With small
SOI adjustment you could increase low end torque and improve consumption.

[clio_williams]

18- 22 hp possible

[bondiblu]

18- 22 hp possible

On an NA diesel?

[Fec001]

Will try and report back how is that goin'
