Message	I believe the JWT ECU program does not have a separate map for safety boost conditions, but rather copies over the normal map. It is my understanding that it does not stop safety boost from occurring. So yes, someone with a JWT program would not see safety as the result of modified ECU tuning, but would still be warned by an illuminted LED and wastegate boost pressure.

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
