RomRaider Project – This is only do able on certain ECU’s, Like the MS41.0/.1.2 and MS43 to a degree (even though that may need to be sent in to somebody). I suggest you go have a stroll at RomRaider Forums,
TestO – You can try this neat tool developed by Pheno, its a free Live Datalogger Tool for BMW’s. We have used it too many times, it support’s multiple sources & works with Innovative, AEM, PLX, 14point7 etc.
Ostrich 2.0 with Tuner Pro Forums – Is a great piggyback option if you have an OBD I Car and on a budget, Also there is AEM FI/C 6. I recommend going this way if you are using the M122H type of setup and you don’t want to hire a Tuner, that is if you are looking to make more power. There are people who just get away with using an raising rate fuel pressure regulator & AFR gauge, the old fashioned way with low boost!
