removing TCS.

[ejXa q45]

so i had a problem with acceleration i my 92 q45 .i took me forever to figure it out but, i narrowed it down to a problem with my TCS .so i calibrated my TPS and STPS.. but still no luck i also checked the rear and front wheel sensors. and most of connectors for the TCS .so then i tried to put codes from the TCM unit ....i think, idk........... its the one in the trunk.but anyways i could not get the codes to flash on the unit so , i disconnected it and and it runs so much better than it did before i have no ABS but i think i will live .before i had some problems going up hills and accelerating from a stand still and a mess load of other things but now it all seemed to go away . i think the system was in safe mode but not sure. has anyone had similar problems with the TCS system or it being in safe mode. and how do i and or can i remove the TCS completely for good....thanks ejxa

I suppose you could unplug the two blue relays underneath of the battery tray? You would have the SLIP and TCS lights on in the dash. You could pull the bulbs for those lights if you wanted to as well.

Most people's non mechanical TCS problems are eventually traced to using rear tires which do not comply with oem design.

Tires which last longer than 15,000 miles or tires which are over 2 years old [compound changes] are a classic NO NO!

TCS slip rates were programmed into computer for a specific oem tire.

The Q is usually not powerful enough to spin the rear tires unless the tires are not in spec or in wet conditions.
