Hello,

This is my first post, I've been following this forum for a while as I'm interested in "trying" to remap my car, purely for fun, I don't expect to become competent!

Anyway, before I buy a spare ECU for tweaking I was wondering if anyone could offer any advice on my current Revo 1.8T remap. I had my Golf 1.8T remapped with a Revo stage 1 many years ago. Recently I removed the SAI pump, blanked off the combi valve & air box and fitted a resistor to prevent the "pump faulty" error. As expected I now get this error...

P0411: Secondary Air Injection System Incorrect Flow Detected

... I believe the ECU can be modified to disable the SAI, http://s4wiki.com/wiki/Tuning#Secondary_Air_Injection

However, before I attempt this I wondered how I stand with the Revo remap. I believe the Revo has two maps, one similar to stock and the stage 1 map, so do both maps need modifying? More importantly can I even modify the Revo map, I've read they have some sort of protection built in which could either prevent me from doing any mods or worse still mess up my remap.

If anyone has any useful information it would be helpful. I’ve searched around but not found anything useful.

Cheers,

Andy.

That, you can't edit the Revo maps.

Well, you can, but it's not discussed here.  No commercial stuff is man! Go back to stock and do your own, Stage 1 is fast to do and is an excellent base to help you understand.

Stock it back to flash both e2p and flash memory ,then you can do whatever you want, REVO is a mess

if the guy likes his revo tune and just wants to disable sai, cdsls is easily changed in his file.

i dont think much of anyone is going to give assistance in editing another tuners file, especially a major companies file. im just telling you its possible.
