TIP Sensor, how do you remove it, and do you plug it into the Throttle body vac/boost?

Stock one plugged in (wires), but not hooked to anything besides that.

Installed SCT tonight, having issues... How do I put my 3 bar in there, and do I run the nipple to the vac/boost line on the Throttle Body?

Thanks for the help :)

My TIP doesn't have bolts from what it looks like. They're flat looking rivets holding it in?

I know where it's at...

I don't think my solenoid block is hooked up right now :( Can't seem to find it... I wonder if you can buy this block somewhere?

Well, if you have a 3bar you cannot just flash any tune into the PCM, the 3bar should be installed like stock. The flash should be a Stage II or III flash or the PCM will not understand the scalers. Use a stage II flash. and the car should make about 16psi. Get that working and I can send you a more agressive flash.

Well, that spells disaster right there. At a minimum, you really need your TIP sensor hooked up, per the original setup. The TIP does a bit more in the software than most people realize. After a solid week of testing all kinds of setups on SRTs, we found that it needed to be hooked up.

Damn skippy it needs to be hooked up. ^^^^ this statement is true. And resistor mods are bandaid fixes like Kenne Bell "boost a pump" "boost a spark" "boost a everything" and FMU's ect...

Guys, lets do things properly, if you're so short on cash that you cannot afford to do something properly wait until you have the money. When we rig things "just for now" they tend to stay rigged forever. This is an expensive hobby you knew that going in. If you cannot afford to buy necessary parts now are you going to be able to afford to buy a new shortblock later?

The PCM needs all the sensor feedback, and the REAL sensor feedback, if you're "tricking" the PCM; really the only person you're fooling is yourself.
Yes, it will work, no it's not ideal.

Not used in _many_ fuel calculations, but used as a 'sanity' check on the MAP. Also serves functions during limp-in. Used for Baro reads, and if it sees no changes, PCM will lock onto standard baro reading, which really does not work too well above 0' elevation. I have seen it here, where I live at nearly 7000'. Correct on mass flow calculations and especially boost/surge control. If your car is bypassed like a Christmas tree, and that makes you happy, so be it. If the calibration is correct, what's the harm in having it connected? Anyone using a SCT setup knows they do not have to run their car with these types of compromises.

By no means am I advocating or even condoning APG's TIP bypass. I trying to comprehend the TIP, the calculated mass air flow, and VE table roles in the engine model. My hang up is, if a VE table exists, why use bother calculate mass air flow using the TIP/MAP differential? Mass air flow can be calculated by VE, rpm, and pressure ratio.


Ohnestly I think AGP is being short sighted if not just lazy their "tunes" by working around the TIP, if indeed that is what they are doing (haven't had time this mornig to independantly confirm this.) If true, its a shame AGP is forcing their customers throwing away the most sophisticated, comprehensive, not to mention free, Electronic Boost control available to them.

Agreed. TIP has many functions, and is no less important than MAP. If it is not working right, expect fuel mixture issues as the NGC runs home to momma, wondering why the pressure twins (MAP and TIP) are so far apart. Boost control is wacked, and expect a lower threshold of OBS. Mass airflow is not calculated by MAP/TIP at WOT, but it is used for surge control, turbine speed calc, and throttle based enrichment at part throttle. I really do not see how one could even be lazy in calibrating without it. To me, it seems like more work, not less. Then again, I suppose someone gets to sell a TIP block off/removal kit? I don't know. The more you work with the NGC system, the more you see the wisdom gained from over 20 years of Chrysler engine control systems. It's a far cry from the 1984 Chrysler Laser.
