I must have spoken at least 10 companies, some are not interested "we just do diesels" these are the ones at guess don't want to try too hard. Others all have different opinions which is quite amazing if you think about it, "piggy back won't work", "piggy back is the way", "cannot adjust the ECU"...... I have heard it all now. With what I have heard and been told I can only come up with one statement. All options WILL work its just how much effort has been put into R&D thats all.
This of course still leaves me with the car in the garage still, I will post in the tuning section, in the mean time also I will fit another lambda boss just in case, ready for a AFR meter.
