Message	JWT just eliminates the safety boost fuel map and makes it the same as the higher boost one. The logic is still there though. They do this because when you put an ECU in and a boost controller the safety boost function no longer works because the stock solenoids are taken out of the equation. If the ECU switched to safety boost map but you continue to run higher boost it could result in damage to the engine. The problem with the safety boost indicator LED is that it will blink on and off when you are on/off the throttle which I found to be very annoying. later, eric ^Thanks for hosting Genic.^

The safety boost function still works. I believe - Eric(NJ) 14:19:59 10/31/07 I think the circuit designed here takes that into account - jcieslik 14:25:38 10/31/07 Yeah, that's the circuit I was originally going to use but I - Eric(NJ) 14:40:41 10/31/07 Correct, the LED in this design will not illuminate at idle (n/m) - zgene4 14:54:53 10/31/07 As long as that is the case then I would be interested. (n/m) - Eric(NJ) 14:56:43 10/31/07 I ran in safety boost for months with my JWT ECU. - rojoloco (Yokosuka, Japan) 23:24:55 10/31/07 Sounds good. $40 is a fair price for a warning of an issue - Barry'z (NJ) 14:29:35 10/31/07 sluggishness and 7 PSI boost are pretty obvious - vorpalZ 14:33:39 10/31/07 Re: sluggishness and 7 PSI boost are pretty obvious - zgene4 14:55:47 10/31/07 What triggers safety boost? Is it the knock sensor - AZHeat 14:44:55 10/31/07 Knock sensor and coolant temp sensor can cause safety boost. - Eric(NJ) 14:48:15 10/31/07 It's really not needed - ZCulture 15:20:07 10/31/07 Very cool, I think I'll do that this weekend. (n/m) - Barry'z (NJ) 15:35:18 10/31/07 I'd probably go with this - turbomaniac 15:47:28 10/31/07 I wouldn't mind a visual confirmation of safety boost. (n/m) - Eric(NJ) 16:33:19 10/31/07 Put an LED in parallel with the relay. Done. (n/m) - MixManMash 17:28:55 10/31/07 If you do that then you still run into the same problem of - Eric(NJ) 17:38:21 10/31/07 and it would illuminte everytime you let off the throttle - zgene4 17:41:44 10/31/07 True. You could use any comparator circuit - ZCulture 17:59:03 10/31/07 in english please - zgene4 18:53:53 10/31/07 Yep, looks like that is the better option and saves me a lot - zgene4 17:42:37 10/31/07 Re: EBC users: Any interest in a safety boost warning device - Z-Tech 16:25:30 10/31/07 Re: EBC users: Any interest in a safety boost warning device? - Hipendicular 20:54:43 10/31/07
