how does the stock tip sensor work with a 3 bar map?
The TIP sensor is only used to measure the WGA pressure. So, it never needs to read more than your spring pressure. As long as you don't run higher than a 17 psi spring, you can use the stock TIP sensor just fine.
im very excited to try this out tomorrow. im gonna try the 14 psi spring, then switch to the 9.
Awesome let us know how the 9 works out.

Ok so I've been messing with my newly installed boost box on the 1.29v software for the last couple of weeks.. stock map/tip sensors. I'm having a little trouble with keeping the spring pressure to stay constant for more then a full day.. after a few spirited pulls down the highway the boost box seems to reset the spring pressure and causes a hefty boost spike... currently i have the boost tables on map A set to 10lbs in first, 15 in 2nd and 18.3lbs from 3-4th gear.. Gain is set at 2 .... Learning Range is at 3...Over boost is set to 18.5...and with the spring pressure at 6 boost levels are right where I want them, however like I said before this doesn't last and eventually spring pressure changes on its own back to 4.3... I am running off the map sensor option.. would this affect how the box responds to the changes in spring pressure?? I haven't tried running off the tip yet...what should the voltage be set to? thank in advance for any input

Do you mean the TPS? You can set it to TPS based control. 2.3 V should be reasonable. That is almost WOT. Then it will only boost at WOT, which should work well.
When do you get the boost spike? Does it spike above 18.5 psi? Trying to hold 18.3 psi with the overboost at 18.5 is probably going to be near impossible. There will always be some overshoot and it will probably shut down the boost almost immediately.
One easy thing to do is lower the gain to 1. See if that helps.
If not, try setting it to 0. That disables learning altogether. Then you will have complete manual control over the spring pressure. Just set it to 6 and go.
Anyway, describe exactly what conditions cause it to boost spike and if you are hitting the overboost cutout and I'll see what we can do to fix it.

Also, did you notice if when you read the spring pressure it was right after a long pull right out to high RPM? If you ended right at high RPM, it probably had to lower the spring pressure a down to 4.3 psi so that your boost would stay up as the RPMs climbed. Then if you got back in it down low it probably overboosted because at the low RPMs the "effective" spring pressure was higher (6 psi).
I am aware of that situation happening. I am working on a solution for it. I am pretty sure I know how we can deal with it.

Yes I meant to say TPS, I'll set that up later today @2.3v and I'll let you know how it goes. Boost spike's well over 18.5; when the spring pressure is at 4.3 it will overshoot about 5-7lbs more then it should. When the spring pressure is set back up to 6 it spikes about 2-4lbs more...i like having a little overshoot. Thing is, I'm not sure the overboost cutout is activating because I've been boosting about 20lbs and holding beautifully...this may be happening 'cause of my spring pressure setting.... If i set the spring pressure at 10lbs which is more or less what my wga is set to.. then all systems normal boost doesn't spike....Before setting the box to run off the TPS I will set the gain to '0' and run off manual control for now.

That sounds just about right. Usually after a pull I'll let off at the top of 4th then occasionally coast back down to a reasonable speed and go again for a 3rd gear pull with the boost overshooting my goals.... there have been a few times where the boost remains constant. Mainly it seems to happen when I shut the car down for a bit then go back out for another pull and I'll notice the crazy spike in all gears....
I'm glad to know this isn't the first you've heard of this situation and happy to hear you are already working out a solution +11ty for N2MB.. Thanks for all the help .. for now I'll be running with the learning disabled by setting the gain '0'.... I'll report back in a few hours.
