As the title state I am having a code 11. My car does not overheat, in fact the cluster temp gauge does not go above half way at anytime. I do have a additional water temp gauge. When the code 11 comes on its always at 220 degrees. I have done research and the only info i can find is that code 11 is a Hondata overheating safty measure turns on at 220 degrees that Hondata provides with their s300 software. My set up is a 92 eg SI with a USDM GSR T4 turbo p28 Hondata tuned by Bisimoto about a year and a half ago. I have had no issues until about a week ago. I have changed the thermostate, fan switch, and I have checked to see what temp my fan switch turns on (180). I have also checked coolant level they are fine, changed coolant last week to be on the safe side, just changed oil last week, oil levels are normal. I have a fluiduine raditor with less than 7,000 miles on it. The fan I have also has less than less than 7,000 miles. My car is not daily driven. I have no leaks of any kind whatsoever. I'm hoping it not a bad head gasket. Has anyone encountered this same problem if you have your input would be great.

BUMP from the past! I have the same problem! So what's the conclusion of this?

 

Did you read the first post or just bump it? He suspected a bad head gasket. Do a compression test.

Orrrr.

You could have looked on the Hondata forums.

Head gasket is fine. Yes, I read it and the link you posted before. And "ITR909" never concluded his findings. Just wanted the lastest update. Is that ok to ask?

 

I have this issue now and think I just figured it out. When I have the Hondata on the Display screen I double clicked the ECT and some squares came up on with parameters in it and the value max is set at 200. I;m gonaa try it and see what happens. That being said, what is then considered a "high-temp" for coolant to cause concern.

 

220 is cause for concern
