Bit of a strange one with my astra J 2.0 cdti sri. My digital speed and analogue speed used to match pretty well but now are well out with the analogue reading approx 10% faster :lol: have compared to GPS and digital is reading 2mph faster which I am happy enough with.
Also rpm seems...
Just got new astra few weeks ago and seen there is no trip computer. Done some research, ordered new speedo set with the mid-level display.
Anyone know if its simple swap job to get the trip computer to work or more is needed and does anybody have a guide how to remove the speedo...
Just joined the forum so this is my first post!
I have an Astra H 1.4 SRi, and yes I do regret not going for a bigger engine, however I love it so please dont bully!
I only intend on keeping the car for another year or two so I'm not going crazy with the mods.
Im planning to do my smd conversion this weekend,
few questions i have are-
when i take the speedo off and then re connect would i have to reprogram it etc
same for the BID screen...will that need re peogramming too?
