If the bottom box is not ten then you are good. You don't want it to be ten at crank, more like 20-30 -- thought I would clarify.

I have similar issues b/c I have a BS3 and have been fighting with the cold start without much luck. Here are a few things I've learned along the way, but I still can't get it to fire like it should when cold. Apologies if I'm repeating things that you know already. BS3 has a DES IAC and an ACT...

Thanks Eric. Let the troubleshooting begin. Good to know it can work with BS3.

Cool, good to know. Any BS3 users out there want to weigh in?

Sorry for the stupid question, but do standalones (e.g., XFI, BS3) work with cruise control? I have a BS3 and no cruise control. If the answer is no, has anyone figured out a way to get it to work?

I've got in on my car, and it's a good system. The interface might be a little out of date, but the processor is solid and it has a lot of capability. As stated earlier in this thread, there isn't a lot of support; there is a good thread on BS3 on YB.com b/c a lot of folks over there run the...

It's the IR 1/8" valve from grainger that jay recommended. Part # P251SS-012-D. Before i got the solenoid to work i was pretty consistently getting 7 psi, but I can try unplugging. My gains right now are low to the point of nothing, so I should be able to tune them with the min and max dc for...

I don't know. Is that the next step? It is a single solenoid plumbed the same way as Eric's.

Need a little help from Bob or others tuning the ISAC boost control. Older versions of the ISAC used prop gain, int gain, and deriv gain. The current version uses spool gain, anti overshoot, and run gain. Are these the same gain parameters with different names, and what should start with to...

I think this is your answer on the wiring question, which is Eric's response to my original question. "I believe the instructions might have things reversed between the switch input 1 and input 2. I have the grey/orange wire running to the low level of the tank as well, but I did the selection...

Okay, I will try to figure that out. Thanks for all of your help -- I'll post back with more later.

I tried 4 ms without being warmed up and it cranked for a long time. So I'm thinking that's not enough. Drove it to the gas station, not fully warmed up but close, and it cranked on 2ms and it fired about the same as 3.5 ms. So on the warmer scale, I'm thinking of keeping it low. Once I...

Stock ignition system (maybe COP next year). Fully warmed up it's 4.5 ms and 8 ms for 77.9F. The base tune was 8.8 ms and 17.6 ms for 77.9. I keep taking it down, just don't know how far to go. Base tune (from different GN tuned by BWR) had smaller injectors and motor wasn't as big. I'm...

This thread has been very helpful. To clarify one point, I have min and max for TPS, RPM and boost. I'm guessing set the max all super high and the min in the trigger range, then when I let off the autosave will work. Something like this: Max TPS 5 Min TPS 2 Max RPM 8000 Min RPM 2000 Min...

I've been tinkering with the cranking table and IAC to get the car to start without a lot of cranking. The car has 96 lb injectors and is a 274 cu in Stage II motor. Could someone share with me their experience for the cranking table for initial setup (around 77 degrees or more) as well as...

One solenoid it is. Thanks a ton for the help. In looking at the screen shots, Bob has higher spool gain, anti overshoot and run gain. What's the reason -- different type of gate, i.e, not external? John

I'm in need of some help with the boost control feature of the ISAC. I have a TurboSmart wastegate and BWR 3.5 downpipe with a dual solenoid setup. The spring in the gate is 7lbs, which is about all the boost I'm making right now. Under the config tab, I have solenoid 1 set at increase and...

Well, I finally got around to looking at the wiring and discovered that the green MAP wire was wired into the LC-1 wideband wire. So with that fixed, the ISAC is working. I also wired it following your outline above Eric. Two terminal blocks, relay to the battery, etc. Should be good now...

The BS3 is showing rich on the logs and no where near that kind of boost. I think I need to follow your approach and have separate grounds to the block for the ISAC and one more for everything else (total of 3).

Hey Eric -- It's the same config file that I posted above with the low triggers. I'm thinking my grounds need more attention. John
