IS300 standalone with stock ecu problems
Hello, I tried to search for solutions everywhere, but with no luck.
I am installing standalone ecu (Ecumaster EMU Classic) leaving stock ecu (to have working all interior gadgets). But after first start-up I noticed that coolant temp gauge doesn't work and oil press/level lamps are 'on' all the time.
I relocated stock ECU to glove box, so I needed to rewire all the necessary wires to it: chassis grounds, engine grounds, ignition, to EFI relay, +12V, all immo related wirres, all A/C related wires, CRK/CAM sensors (with sensor ground), oil press and level signal wires, coolant sensor wire (with sensor ground), both multiplex wires, alternator status wire.
I tested oil press wire if it gets signal from engine (it does). Also my standalone ecu shows coolant temp perfectly (connected parallel to stock ecu). Looks like other gadgets are working (didin't checked fuel gauge so far).
Is there anything that I missed connecting or is this just the unsolvable issues when using this combination with custom ecu?
Thanks in andvance!
