Re: Nissan 350z S6+

George, You are of course correct that the ECU will run the engine - the dash may not work then, but the engine will, and if the car is a manual then it will most likely drive as well (unlike, say, the GT-R, which will not). I see your point regarding the OEM ECU and the need for new wiring for the ...

Re: Nissan 350z S6+

George, I'm not sure what you're trying to achieve here. Let me explain : If you take an S6GPPlus as it comes in a GENERIC build, it will not work on a 350Z due to the CAN bus integration. You would have to buy an S6GPPlus with 350Z build, so what you may save here is the cost of a pre-fabricated an...

Re: CAN output to Plex micro SDM

Ed, The S6GPPlus has two CAN buses, one is normally a link between the S6 and the Plus boards, and the other is normally for external use. In order for information to make its way to the Plex, it would typically go through the Plus and out on the other side, at 1Mbps. This will work unless the Plus ...

Re: PWM Fuel labs Prodigy questions

Am I missing something really simple? Yes :) Low Side output duty is time spent ON, which means LOW. The duty in the fuel pump manual is most likely time spent HIGH, hence the inversion. IGN (in TTL mode) and HBR output duty (in half bridge mode) is time spent HIGH. Everything else is time spent LO...

That may well be but I can't see it in the logs that are here...

Re: Bosch LSU 4.9 sensors dropping like flies

Ed, The plot thickens. Looking at the datalog from 16:46:39 we see that the LSU feedback is pegged at ZERO. That should mean there is NO drive to the heater since the cell temp is already way too high. That should be impossible since the sensor was clearly cold since it was not reading at the start ...

Re: Bosch LSU 4.9 sensors dropping like flies

Ed, the more I look at the logs the more I am concerned about sensors being damaged during or just after start. As mentioned to Ryan on the phone, a Subaru manifold is just a few centimeters short of the distance between London and Glasgow - that is before the gas gets to the turbine, which will coo...

Re: Bosch LSU 4.9 sensors dropping like flies

Ed, Apologies for the delay in looking at this - as previously explained I have a lot on my plate right now, and I am not part of the support group. I have now looked through all the logs. The first lot aren't so useful since they don't show the LSU feedback, so we can't draw any concrete conclusion...

Re: CAN termination

SDM-X00 is my shorthand for SDM-300, SDM-500 and SDM-700, those being the range of Plex dashes that are compatible with CAN running a Slave Link :)

Re: Overrun fuel cutoff - not happening!

Stevie, thanks for confirming you are seeing 100% trqFuelSev in your logs. With regard to whether fuelFinalPri should drop to 0, that is a matter of classification. If we think about the steps taken to get to fuelFinalPri1, from the ECU's perspective it does not have control over any of it (well, OK...
