Well I found out I can enable the boost box via MAP instead of TPS which gets its signal from dlc... I'm going to call n2mb soon to confirm this and see if they can cut me a deal on a boot box lol, it will be my 3rd time buying one and I've gotten them at least 15 sold locally that I've installed! I'll even rock a dam n2mb sticker on my windshield if I need to!
It's a piece of cake guys. You need to jump the tps signal wire to the same pin on the arm harness and it will work. The other inputs work because they are still on the bus for the gauges . The tps will be too after you run a jumper wire
Sorry to bump an old thread, but by jumping the TPS signal wire are you using the stock TIP sensor or do I need to match the TIP sensor to the 3.5 AEM MAP sensor?
Or is it easier to just control boost based on MAP values as I read in different thread.
I had a local install aem ems and car runs good but now my boost by gear doesn't work he had to put a MBC on any reason why this would happen ? Boost by gear doesn't work with ems?
Need to see if all of the inputs to the BB are still connected. Also telemetry mode must be off as the BB uses OBII data from the stock PCM. This applies for the AEM EMS that is plug and play. If you have a different set up then it may or may not work. Most of the info you seek is in the BB manual. If that doesn't help I'd suggest to contact n2mb. I have spoke with Jay in the past and he is really helpful.
I find it odd that your tuner didn't set up the boost up via the ems. A MBC is kinda cheesy when you have an advanced device under the hood.
Are you using the serial data stream gauge from AEM?
Edit: just looked at the factory manual. Looks like the BB uses the PCI bus from the OBD connector. I know that the ems will send either obd data or telemetry data over the SCI transmit line. I have no idea what is transmitted over the PCI line.
