oversteer

I'll try get some more info from the Motec guy, he says he has can template for Motec C series dashes that I would need to know my way around the software to use... The pump is a brushless thing with all sorts of protections monitoring and smarts, the heat sinked control board attached to the pump is just about as big as the pump it self lol, so a solid state relay wouldn't work. Running the pump in 3 modes would be good enough, having infinite control over motor speed is not necessary. If I could work out the Legacy command CAN structure to send the pump % start, how would configure and use that in the link ? Cheers

Adam - any input on this ? is what i want to do possible and or is there enough info in that document ? Barge - I take it from your comment that a pwm output over CAN is the way to do this ??

Hello I going to set-up several switches on digital input channels to do various things, planning on making a switch panel with led to indicate switch status....switches will switch low to digital in and also light an led that gets its ground from the switch.... any issues with this ? ie the link might see 12v on the digital input through the led when switch is off !? Cheers

Ok i have been pointed in the direction of the attched document, seems to detail can addresses and bytes, but i might need some help on how to configure this in the Link !? Adam - does that document contain enough information ? Cheers Justin EMP pump data1.pdf

Ok thanks for the suggestions re fuel pump, i should be able to do what i want from that. I should have elaborated more but i have already wired the 4 pump relays to a separate aux to control them that way and a FP sensor. Not sold on the solid state relay idea's to variable speed the pumps as I'm not certain they will like that and its worth the complexity and set-up time to get it all right. As for the EMP pump the whole reason for CAN connection is to run the pump variable speed, it already has an on off wire which runs the pump flat out with no CAN connection, its a big pump and i don't need to blow 25A running it all the time when cruising on the street(pump circulates coolant from a AC/refrigeratively chilled coolant reservoir through WAIC) . So I'm told, someone using it with a M150 has CAN controlled it with this system, may have to try get in touch with them...

Ok, I'll have to use a DPDT relay then to get it that close and not have to screw around when connecting laptop... which will be in the car a lot during tuning and testing etc. Is there a pinout somewhere of the connector so i can find tx and rx ?

Hello I'm using a EMP WP29 on a interchiller set-up and would like to control pump speed via CAN, below is a link to spec sheet that details CAN protocol.....how would i configure this in a G4+ Thunder ? I have setup wiring for pump to CAN2, just waiting on correct pins for DTM plug. https://www.emp-corp.com/media/MarketingMaterial/WP32/SpecificationSheets/WP29-32SpecSheet040915.pdf Also i am using 4 Walbro 460 pumps and want to stage them, what's the best way to go about this (fuel pump config doesn't seem to have much flexibility, but i am new to link !)? Likely need flow from 2-3 pumps under full load/boost on E85, 4th is a spare... Pumps also have current monitors(using arduino 30A current modules that produce 0-5v signal) wired to ANV inputs, any suggestions on best way to configure these inputs to display current transposed from signal and use in protections ? ....I've had pump failures in the past that cost an engine using expensive&hard to source/replace pumps, the walbro set-up is cheap enough to carry multiple spares and current monitors should hopefully indicate issues early....

Brilliant thankyou, it works. I assume if i install a switch on the dash cable i can flick it off to connect with PCLink rather than pulling plugs ? Is there any disadvantage to running the dash this way rather than CAN ?

Hello I have a G4+ thunder and a old Racepak IQ3 that came from a car with a old VIPEC, it has a VM 230 EFIVIPEC module, which if my googling is correct is not a CAN interface, its serial. The plug on the EFIVIPEC module plugs into the thunder(has 2 serial/CAN ports?) I saw a post on here where someone was using Racepak serial thing with a Fury, and i have tried to set Datastream to requested short and 57600 baud....doesn't seem to work ! Can what i'm doing be made to work ? ....without buying the Generic EFI Racepak module ? What exactly are the 2 round ports on the thunder ? was hoping if this works i can have laptop and Racepak communicating at the same time. ? Cheers Justin
