ive contacted sinister performance and they informed me that they can custom make a dual chip set up. what this is its a " mem -cal adapter. it would allow me to run my fans at 160 deg with acompanying t-stat in the brutal vegas summers. and to switch in a chip made to run the fans at 180 deg with the 180 deg t-stat for the mild vegas winters. all i have to do is remove the 160 chip from the mem-cal circuit board (moats-G4) and instal the 180. all this with ,egr delete,cat delete,cai,provisions for higher air flow from ported heads and manifold. what do you think?

Well from what I've read, the biggest issue with the 160* is that the Knock Sensors aren't programmed to operate until the engine reaches 162*, so unless you are 100% sure you are knock free, you're basically risking your engine from grenading.

if it floats your boat go for it... but be sure they proram that PCM to enable the knock sensor at lower temp say 135-140F.

if you are running too hot in the summer consider replacing your radiator if it is old - the aluminum develops a layer of aluminum oxide internally that tends to insulate - so it does not dissipate heat as well over time. For some drivers this does not matter, for others it does.

L67, I agree for '96 and up, but I'm not sure how that applies to Series 1 setups. There was just somebody else having trouble we think due to their 160 tstat in a '95.

great advice. ive been running a 160 t-stat for two months now in the vegas summer and the needle hovers at the middle mark,sometimes it creeps a little past but not near as bad as with the 180. and the rad is new. ive emailed ryan @ sinister and asked about the knock sensor being reprogramed too. ill keep any one interested posted....

the fans run with the ac. ive gotten out popped the hood and was blown away with the heat and the fans were not taking up the call! when you say "jump the fans with full 12v" what do you mean?

i hear ya L67. but sinister can reprogram the chip to do this. they really sound like they know what they are doing..and they will work with me if needed...
