318is chip dinan vs conforti - BMW Forum

theironm0nk · 12-05-2005, 12:29 AM

they both offer good qualities but which one is better for street driving?

Dinan: HP11@4500
torque19@2500
no governor

conforti:HP11@5500
torque19@2500
new rev is 6900

I'm leaning towards conforti but if my chip is soldered then I might have to go to the dealership and buy the Dinan.

The Torque is the same but teh HP is different, so the real question is where along your power band do you drive? If you are not aggressive it looks like the Dinan would be better, but if you are more aggressive the Conforti might be a better pick based on the info. If i were you I would try to find a dyno sheet for each to see the power and torque curve, then think about your driving habits and see which fits that best.

Side note not dealing with street driving: I am not sure what kind I have (installed by a previous owner) but it has no rev limiter at all... and that is how I found out that I had a chip... around 7.2k rpms (yes the needle was buried). For auto-x and the like it is nice to have the limiter so that you do not have to keep on eye on the tach when you have to catch first for a tight turn. But for street driving I do not think it would make a huge difference.

so if I go with the conforti my car will still be electronically limited at 120mph.

Even if it did limit it to 120mph ur car does struggle to get there

i got the Conforti chip in my 93 318is... I actually had to get it soldered in which they dont recommend but it cane easily be done. i brought it to a place KMD tuning and they did it for like 70 bucks which was well worth it. Anyways i found that when i first got the chip in you could easily notice the gain. it basically just got rid of the flat spot when taking off with the car... It was a solid rev all the way from 1500 to 6. Thats what made the difference in power. Then a few weeks after having the car i noticed that it stopped doing the solid rev and it seemed to have went back to what it used to be like? maybe because i got used to it. But the only thing i suggest is do not do this with an Automatic without getting the Trans chip. It made my car overall slower because when it shifts into 3rd it COMPLETELY FLATSPOTS the car and the revs almost drop instead of rise. When i ran the quarter i did an 18.5. And i know i have an automatic but really thats pretty slow hahahaha being that i had a perfect launch. I have an intake with K&N and the conforti chip. everything else is very well maintained. i would like to see how the chip reacts in a manual car.

No Governor? I'm probably not thinking of this the right way but that sounds bad if you're using your full rpm range, that your engine would just spin until it can't anymore. How does Dinan describe it?

There is no rev limiter I believe is what he is reffering to. So your car's rpm will continue to go up until the engine destroys it self unless the transmission shifts. If you have upgraded internals that can take higher rpms, then it is good to have because then you can use the full potential of the car. If not you need to keep a carefuly eye on it while doing really aggressive downshifts, tracking the car etc.
