Hey all, after I got my map a little while back Im curious to see what others with remapped 140 TDI's have ended up with, I would really like to see graphs as with my map the power is good then seems to start dropping away at 3000rpm (just when its getting going) which to me seems too early, Ive included my graph whats your opinions?

The Blue lines are Torque, the Red is HP

Dotted lines are standard, Solid is the Remap.

Nice smooth power & torque. Figures are healthy too.

Does seem to drop off a little early (peaks at around 3300rpm) but I wouldn't worry about it.

do not know much about 140 remaps but I woul have thought the torque should have flattened out for a while before dropping off. Yours seems to go up and then straight back down. Be interesting to see other graphs too.

My thoughts as well.... the torque curve looks like a BHP curve. I'd like to see it flatten off and hold for a while before dropping like that

thats exactly what I mean, it just doesnt feel like it holds it enough to benefit from the extra power, it feels like it did when it was standard after 3000rpm, and whilst I know its a diesel and not high revving, Ive just been lookign at the Revo map here:Performance ECU Tuning Software by Revo Technik

It looks more like what I was expecting,

The turbo is strong enough to hold high boost to at least 4000 RPM, It should then drop from 4000 to 4500. If I was you I would ask your tuner to either add a bit more boost or hold the current boost for a few more RPM's.

Saying that Dyno's are a bit of a lottery and figures/graph curves can be altered by something as small as how the car is strapped down.

You should be able to feel on the road exactly when the turbo has peaked and when it boost begins to lessen. It should be approx 3800-4000 RPM, where you should then notice the last few hundred RPM's have less Turbo punch, it might still pull to 4500, but it will feel less strong in it's delivery then from say 3500-4000 RPM.

I think the curves look just fine. The 2.0TDi can take a lot of fuel between 2.000-3.000rpm, but the turbo is not strong and if you give it more than 1.5-1.55 bars it will not last long. With 1.5 bars you can not get more than 175-180hp if you don't want a lot of smoke. I normally give them app. 400nm (don't know how much that is according to your terms) but "only" 175hp. I never have customers complaining about defect turbos. I doubt Revo makes 185hp without problems with the turbo or a lot of smoke. In my world it is more important in a TDi what you have between 2.000rpm and 3.000rpm than what you have between 3.000rpm-4.000rpm for daily use.

Dont get me wrong, Im not unhappy with the peak figures, its just that they are there for so short of time Im not seeing much benefit, I would be interested to see other graphs. My torque Peaks at about 2900rpm and immediately drops, I would like it to hold the Torque until about 3500.

Who mapped it?

I normally give them app. 400nm (don't know how much that is according to your terms)

295 ftlb

sorry to bump this, Im thinking of going for a Mufflerectomy and RE-Remap to make the figures the way I want, would it be worth the cash you think?

Can I just ask, did any of you find the top speed of the car any higher after the map?

Who really cares about top speed? It's not like you should ever get anywhere near the top speed of a standard car, unless on an unrestricted autobahn.

I just curious really, my mate was talking about his 307 hdi that had previously been around 115mph after a tuning box was capable of 125mph plus, I was curious if the map for mine would make it also higher than the booked 129mph.

Top speed is affected mainly of the drag coeficient of the car and the engine power.

Look at engine power derived at highest gear in top speed.

Compare this point with modified power figure.

If the new power is higher, you will get higher top speed.

If the new power is lower, the result is lower top speed.

stands to reason I guess, maybe Ill get to try it out on an autobahn some day.

So do you guys think it would be worthwhile getting a re remap again? was going to try to get the following done:

torque no higher than 300lb/ft but held at that from 2400rpm to 3800rpm

Hp slightly raised(prob will be with the torque being held for longer), maybe to 190

would it actually be possible to do these this in a precise manner?
