How do I eliminate the 18psi limp mode with my 180/77
My car will hit limp mode as soon as I hit 18psi of boost and then I have to turn the car off and restart it otherwise the car will just bog down anything over 3k rpm. I have all cooling and exhaust mods necessary. Will a tune disable or raise the limp mode to at least 20psi? What are you guys doing whoever has this same setup? Or do I switch back to a 180/83 setup?
In "lay" terms:
Say a wealthy investor tells his "nanny" that he's measured at nine inches. This is all well and good, per se.
---Except, he's measuring from the exhaust, to the tip, so-to-speak. At the end of the night, the "nanny" sees six inches, even though he's really carrying the "extra three".
This is how devices such as these can help this situation, if you follow the euphemism.
Be advised, you will have to re-scale your ECU, to make everything play nice (since your ECU is really only programmed to see X amount of pressure).

Hope that helps.
Certainly are pushing the threshold of the superchargers efficiency.
You splice into to the map sensor cable and set the voltage to @4.5v......ish. ECU goes ape sh*t once signal hits 5v with high boost. A dyno tune is always good to have done after install so you can get the afr's in check.
thats a Weistec blower and fixed pulley with a EC tune --i wonder why the fixed pulley with OEM blower has issues like the infamous hiccup
its an enigma

after driving normally for 200km I had the same problem. It is not taking more than 3000 rpm and more than 140 km/h.
I restarted the car and was back in normal. No check lights on the dash.
any idea what to do?
This was my first data log in a recent mile event a few weeks ago. I built an entirely new intercooler system and was running it on the CLS for data. My heads were lifting and blowing coolant out the reservoir during these data logs. These figures were taken with the Map sensor (clamped) after all three water to air intercoolers. I should have over 20 psi once I remove the factory intercooler (working on intercooler revision #4)
Map clamp only. No fairy dust or bullsh*t tuning claims.
Yeah, the IAT's? 89 degrees at the airstrip. Engine Bay tank was iced down (2.25 gallons) and using 49 meth/ 51 water. Wicked burn out jumped my IAT's a tad and sitting in staging didn't help. Regardless, not a system out there could do that. That's over a mile @ WOT. Just say'in?
