Hello Adurer and all, As I said before, my Octavia TDI PD has a onboard trip computer, and that gave me the idea of build and program one for my 1989 Mercedes with a diesel engine and a radial pump. Two fuel flow meters, and an Arduino board. But my approach didn´t work. Very probably, the DFM meters didn't exist (for me al least). Then I got a MPGuino trip computer, and was trying to get electronic signals from my car for estimating fuel consumption. Adurer gave me very good links of fuel meters, of professional level, that are the solution to my wish, as can produce a differential signal directly. No need of two fuel meters. Besides, now I am working in a different car, a 1993 Mercedes with a linear pump. Looking and the videos in Techonoton site and in my car's pump, they use the same kind of banjo fitting present in my IP. So, now it is a matter of study the manuals and get the money for purchasing the differential fuel flow meter and instalation kit. This is first step. Besides, I have to install my MPGuino in the car, and input to it the VSS signal and the differential DTM meter signal, and I will have a very good estimation of real time fuel consumption and yield. My Skoda Octavia is giving me about 40 km/l at 70km/h in 6th speed, on a short flat road, cruise engaged, starting measure at 70km/h, not from stand still. This is remarkable good. Isn't it? At 100 km/h it yields 23 km/lt in long trips, as a mean, door to door. Very sensible to sport driving, sprints and such, yield drops substantially. And the driver can see it thanks to the onboard trip computer. My wife uses the car and she gets about 18km/l where I get 22 just watching my trip computer. Just by use a better driving style. My 1993 Mercedes is giving me 10 km/l only, while it should yield 12km/l. I am evaluating several mods to it, based on the experience of other drivers. But on some points they have different opinions. I like to test mods in an objective way, and the only adequate way is using a trip computer. So I can evaluate fast and test many things without having to wait for many tanks of fuel. Best of all with Diff meter, I may not need a programming interface between it and MPGuino, as it may understand the signal. This would be optimal. Thank you again, Adurer, and I will keep this Fórum updated on my Project progress. Oldbeaver

Why do you say so?

Masster, Nice Project, I offer to help you with it. Unfortunately, I don´t see the figures you posted. Well, I have a Skoda Octavia with built-in computer, however, I also have a diesel Merc without it (W124) and want to develop a similar device as you. Please post again yr pictures or send them to me. Don´t give up on yr Project, despite other's opinión. Greetings, Oldbeaver PD: I have made a lot of research on this, haven´t find an feasible and economic solution, so far. I think many people would benefit from yr Project.

Well, the Octavia VRS and the Octavia TDI may surely have the same suspension. I have the TDI. I back this topic because I suffer a little from my low back, and find my Octavia a little hard. I wish I can soften the suspension, both, front and rear. I don´t want to change this car, it is really good. I am getting more than 50 mpg (imperial) and the car is very reliable. I think I am going to improve fuel yield an additional 17% with a recent tune of cam distribution I made this week. This is a magnificent car, good to keep it for long. Difficult to change for a different car. I am sure there are several experienced people on the suspension topic in the Forum. But, almost all of them are looking after sport cars, and devote their knowledge to make suspension more stiff, the opposite we want. Hey experts, youngsters, give us a hand ! From the very little I learned on the net about the subjet, longer stability bars should soften suspension. This will keep all the rest equal, same height, same coils, same shock absorbers, softer suspension (I think). Making the bar longer is not so difficult, the point is to learn how much. I listen for experts opinions. Oldbeaver

Hello to all! I introduce myself as the happy owner of e second hand 2009 Skoda Octavia 1.9 TDI DSG, which is running very well. My main interest so far is mileage improvement. As this beauty comes very fuel efficient from the factory, it is difficult to improve further. At present I am looking a way of complete the undercover which only embraces the front part of the car. Also chiptuning or new mapping of engine may be a possibility. Look forward to hear from owner´s experience and will share my findings. Oldbeaver

Hello, Good post, very detailed. One question: Are you replacing a broke suspension for a new standard one? Or, are you making a mod, meaning you installed an improved one? Please, explain. I have a Octavia II 1.9 TDI and the only trade off for me of the car is the too stiff rear suspension. Do you know any way for softening it? Thank you, Oldbeaver Chile
