Being that the turbos and engine for our 124 are the same as the 500, I was wondering if anyone can point me in the right direction as far as what people are using to increase their boost pressure with these and what pressure people are typically running. I looked through some of the 500 forums but couldn't find anything. I was thinking about running either 15 or 20 psi (provided the stock internals on these engines can take that). Mods would end up being simple. Intake, full 2.5 turbo back exhaust(when it becomes available for the automatic Abarth), upgraded intercooler, EDL, Forge wastegate. I'm just looking to have some spirited fun in the car. :)

The stock 124 runs peak boost of about 21psi. There are several ways to increase boost pressure. Currently I would argue that the best method is with Euro+Drive Lite from eurocompulsion.net. I did the software work myself, and I am quite happy with it.

I'm shocked that it is already pushing that much boost. I was thinking it was around 10-12 psi. So, what is holding this engine back from being a beast on the road? I am planning on getting the EDL when the Abarth mapping is done. That is if I don't trade up for a 4C.

First of all, I have to say that the 4C is just another level of car. In many ways I do like the 124 more, and it's certainly more practical, but in performance there isn't much of a comparison.

OK, boost. I understand what you are thinking. With 21psi the car should be a lot faster right? Well, not really because it doesn't have 21psi WHEN it's making max power, it has around 15. It only goes to 21psi for a short time and then the boost drops well before the rpm point when max power occurs and then drops a lot more from there. That's why in stock form the car feels so dead above 5500rpm.

A Euro-Drive Lite will fix that dead zone...I know.>:)

Any notice on when the Abarth mapping for the EDL will be completed Greg? I'm also curious as to how the peak boost can be at 21 for such a short time. Is this because of the factor actuator creeping open once you get past 15 psi? ( just an educated guess). As far as the 4C, I think I just love the curves and elegance of it. It definitely is not practical though. I test drove it before getting this and it is a pain to get in and out of. It is also a shame that they do not have a manual version.

The factory requested boost curve just drops massively after hitting peak. Fiat typically programs almost all cars with the 1.4T this way, they tend to like lower end punch and a very conservative high end powerband.

The mapping on the EDL for the Abarth will be the same as the base models. At least for the US cars. They're essentially identical, except that the boost curve on the Abarth version is ever so slightly more linear at the midrange, it's almost not noticeable. Other than that, there are no mapping changes to boost, which is what the EDL deals with the most. All of the parts we make will be compatible on both the base model 124 and Abarth 124 with no modifications required.

Now, there is a much bigger gap between the EU base models and their Abarth. But the above will be true for US spec cars.

So essentially you're saying I can go ahead and purchase the EDL for my Abarth now correct?

Hey all, can the same be said for the Australian abarth models too? Any idea?

As in, the EDL will work as the same? (we only have the abarths down here)

Thanks!

Yes, it's the same unit for Australian models. Hey, I am in Sydney right now. Planning on hitting the Burger Barrel in Coogee at about 5pm.

Would have loved to join! but unfortunately I'm in Hong Kong at the moment. Have a few beers for me will you? Cheers! :)
That's too bad. I'm heading up to Narita Japan tomorrow and then over the Shanghai. Perhaps another time it will work out.
