delay accessory for cold starts

I installed a viper 5904 + dball on a honda odyssey, and am having issues with the starting of the vehicle in cold weather.  the remote start wouldn't work at -5 degC yesterday, but i read on another forum, that these LEV/ULEV vehicles, you should turn off all the accessories.  So i went back out, turned the A/C system off, and activated the remote starter and it worked.  Today, it was -15degC, and all day i made sure the A/C system was off, and it worked everytime.

I read on another forum that the LEV/ULEV messes things up because it is trying to be efficient when starting, and hence the reason not to load up the vehicle with all the accessories.  I am quite confused about the relays, which setup should i install to delay the accessory to activate after the car has been started? does DEI sell something, or can this be programmed in the 5904?  I do have a bit writer.

not sure if it would work or not but you could TRY setting the diesel wait timer. This won't delay the accessories or anything, but it will turn the accessories on and get the running before trying to start. That extra delay may allow the voltage to "settle" from everything turning on at once. May or may not work, but something easy to try.Kenny

You could use a 528t timer, set up to delay up to 3 minutes, it will handle 30 amps, one for each accessory wire. P.S. I never checked this but shouldn't the ACC output be off until the remote start has successfully engaged?

Thats a good point. The acc circuit should power up initially but then drop as soon as the starter cranks. Make sure the programming is set for the acc to be off during crank.Kenny

the acc should turn off until the vehicle has started. you must have something wired up incorrectly. temperature should not be a factor at all. assuming you have a data bypass not key in a box, tach connection, powering correct ign,acc wires, i dont see why it shouldnt work everytime. when you say at -5 degrees it "won't work" exactly what is happening?Ted

Procedure should be thus:- Activate Ignition 1 Ignition 2* might even be after starter. Starter 1 and 2 Engine run, then, ACC

Hmmm.. thats weird. B/c I know on all the DEI and Compustar units I've done the acc wire activates for roughly 1 second then shuts off, cranks, and then re-activates... from what i can remember.Kenny

Damnation Kenny you want me to put down my tea, go outside in the freezing cold to my car, open it, turn on the radio take the key out and do an R/S. Sod it your probably right. How about delayed activation for old farts (like me).

I have the Dball from xpresskit.  when it got cold, it would try to start but didn't seem like there was enough juice.  read on an acura forum that i should turn it off the ac controls, and it hasn't failed yet.  Not sure if it matters but this is the touring model, and has the ECO feature to save on gas.

I have it W2W, tach is at the injector.

I found someone on YouTube achieve the 'AC delay using the 528T' in their odyssey, however, he didn't post how he accomplished it. 

I am hoping this will solve my problem.

Did you try just setting the diesel wait timer for a few seconds first? Why spend money on the 528t if that will work. I'm not saying it will necessarily, but its worth a shot. And did you check to make sure your acc circuit was dropping out during crank?Kenny
