LanciaNut69

Hi again Adam, thanks again for your reply and I will look at alpha-n. It’s good to know that the atom has the additional capacity and I think I will upgrade from Emerald anyway and use it or other Link ECUs on future builds. can anyone recommend a UK supplier of wired in units? Thanks again, Darren

Thanks for the reply Adam, much appreciated and maybe I’ll look at alpha-n in the meantime, but do you know if the atom has the capacity to be able to deal with tuning using a small variance in MAP? Thanks Darren

Hi there, I have a Lancia Montecarlo fitted with throttle body fuel injection. It’s an 8 valve twin cam, normally aspirated engine producing around 200 bhp. It has been running on an Emerald K6 ecu, but current changes have highlighted an issue that this old tech is unable to cope with and has proved impossible to map at low load and cruise. The reason is down to a very low vacuum reading (0.23 Bar). Each cylinder is ported for a 4mm tube, joined and baffled before running to a 3 Bar map sensor with links to fuel pressure regulator and brake servo. I am looking to upgrade to the Atom x and need to know if the software is able to read small changes in MAP? I see there is an option for a 1.15 Bar sensor, which will reduce the range but will it be enough? The engine itself is good, with 175 psi across the cylinders and no air leaks anywhere else. Cams are fast road type and do not have a large overlap - for some reason just low vacuum. Thanks in advance and look forward to any help you can give me. All the best, Darren
