Hi guys, I'm almost ready to start tuning an M54B30 (Vanos disabled, M50B25 intake, standard B30 injectors, M50B25 sensors) running on an E36 G4+ plugin ecu. The base map is sufficient to start the car, though unsurprisingly it's running pretty rich. The B25 base map runs a 177cc/min injector, whereas the B30 injectors are rated to 282cc. Presently the engine is idling at around 11.7 AFR, and seeing 9s at WOT. The Master Fuel is currently set to 20ms, am I on the right track thinking that the value should be closer to 12ms to allow for the 60% +/- extra flow of the B30 injectors? Fuel table numbers look to be about where I'll want them to be if I'm on the right track. Thanks in advance

Thanks Keith. Will this convert the table values as well? Sorry for the noob question

Hi, I've been fortunate enough to have another G4+ user share his tune with me but I'm unsure as to whether the TPS fuel map will be the best option. For background, we are both using the BMW M54B30; however his engine has a set of ITBs from an S50B30 and has intake Vanos enabled - I'm using a intake manifold & throttle body from an M50B25 and have locked both cams at 0º advance. Would a TPS map be appropriate in my application? And if not, how do I go about converting the map for MAP?

Looks like I've found what I'm looking for

Hi guys, am having issues with a modified M54B30 running on a G4+ E36 ecu. Engine changes are Vanos delete with cams locked at 0º advance, M50B25 intake, ICV & throttle body, M43B19 VR block mounted type crank sensor, M50B25 intake cam sensor, AFM & charcoal canister delete. Cams & injectors are factory. Am looking for a latency table to suit. So far the only numbers I've come across are here : but I'm not 100% convinced they're accurate. Also, as there are no published values for 7,9,11,13 & 15v I've used the midway point as a guesstimate. Is this regarded as acceptable? Could anyone please share the numbers they've used? This is the first time I've taken on a project like this, your advice & patience are appreciated!
