1995 Del Sol With AC, Turbo, and S300 overheating code 11

[crxb5]

Ok i have a 1995 Del sol Factory B16a3 with factory AC and Powersteering.
I bought the car turbocharged with a homemade turbo kit and previous owner wired a Apexi AVCR boost controller into it. I drove the car like this and had pretty much no issues whatsoever, no cels or anything. I cant remember if i used the AC much though.

Two weeks ago i tore the homemade kit off and installed a go autoworks kit with external wastegate and bigger turbo, intercooler, exhaust etc. I am using dsm 440's with resistor box. I bought a P05 ECU off a friend witht the s300 installed.

My friend street tuned my car after i got it together and it ran ok, no cels or anything for about a week, i cant remember if i used the AC during this time frame or not.

Anyway i drove to carlisle PA to have my car tuned by a reputable tuner on the s300. I drove my car, he istalled the ECU, dyno tuned it, and helped me with one of the wires on the AEM uego i installed then i drove back home. Almost a 300 mile trip home. Car ran great didnt miss a beat, no cels or anything, i dont believe i used the AC as i was driving with the top off.

3 days after getting home. My Slim fan and ZAP dual core radiator came to my house. I flushed the coolant system, installed the radiator and fan, then refilled the coolant, and installed the air intake i made for my turbo charger. I mounted the slim fan in stock location and verified its polarity and functionality. Also i checked to make sure my AC condensor fan worked when turned on, it did.

Now to the problem, last two weeks it seems as if anytime i have the AC on and its fairly hot out, and i drive for more than 20 mins, my CEL comes on, and goes into limp mode with the rev limiter at its throwing a code 11 for overheating in hondata. At IDLE my ECT are 220 F and my IAT's 170 F. I have almost no doubt that the car is actually overheating because the ECT and IAT's coorelate with each other.

For my aem Uego i believe i taped the power wire into the radio fuse in the fuse box, the black wire i grounded to D22 (spliced it in) , then he switched where i had the white wire wired to d14 and he pinned it to d10 (ELD) i believe, he left the other end of this wire open. I also burped the colling system again after noticing overheating and even though a few bubbles came out it still overheats?

So my question is what you think is causing my car to overheat?
- Could he be a problem within the ECU since the P05 (civic CX) ECU didnt orininally come with a car equipped with AC can this be causing some sort of fault or error within the radiator fan cycle?
- Could the dual core radiator i have and the high speed slim fan be less efficient than the oem?
- Could my AC compressor be going bad causing too much load on the system and pressure within the ac lines..
- I know i can datalog while driving then turn AC on to see if it alters the temperatures much but i havent done this yet..

Thanks
I have attached my CAL
Also i will not be able to mess with the car until tuesday of next week because i am currently away from it.

More than likely the intercooler is blocking off too much air flow and the radiator and condensor are just getting too hot from lack of air flow.

That is highly possible, (I just realized i put the lower splash shield on once i got home from tuning, even though i cut a lot of 1 inch holes in it to help it breathe, it can still be restricting airflow. however when i dont turn AC on it seems that the ECT didt go above 195 and the IAT's didnt go above 130. I am going to try and datalog next time with the AC on until it throws the cell..

I am going to cut a 6 inch OD 3 inch ID velocity stack and glue it in my bumper then run a 3 inch duct hose through the CAI slot is in the passenger fender then direct the air right near my turbo and filter. I was also thinking about the hood spacers.

Hood spacers do more harm than they do good. They will increase the pressure inside the engine bay and allow even less air to flow through the radiator. Ducting more air into the engine bay and bypassing the radiator will not help. The air needs to flow through the intercooler, then the condenser, then the radiator....each one heats it more and more and the more air you get to pass through them all the cooler it will run.

That makes sense on hood spacers, however i still believe it will alow some heat to escape even with the pressure difference. At speeds below 20 mph it should be somewhat effective.

Do you reccommend i drive around with the bumper off to monitor the IAT's and ECTs? if it still overheats with the bumper off would that likely mean i may have a headgasket issue?

Also do you think my part throttle tuning might be too rich causing excess heat? Car was tuned on a very humid day and also the hood was open with a big fan blowing air into the engine bay.

What do you reccommend i do? Also my dumptube is right next to my AC condenser and has to be heat soaking it somewhat.

I will post pictures when i get the car back on tuesday.

When I picked up my car today i was driving on highway for bout 30 miles. I had laptop up and was datalogging, it was 70 degress and humid/raining. My ECT reached 195 and stayed there and my IAT were at 110 steady. I Turned AC on coldest setting and hat my fan on highest setting while datalogging and Boom EGT rose to 202 and IAT's to about 130 in less than 4 minutes crusing at 70mph.

Umpon making it to my destination, i noticed that my front liscense plate was blocking a good section of airflow to my FMIC so i removed it. I am planning on removing my Auxilary lights and running a Duct to the Radiatir and Condensor and possibly branch one off to my airfilter, my AFR's seem to be running fairly rich under WOT, possibly to lack of fresh air entering the turbine.

I will do more datalogging and experimenting and will post conclusions if any are made.

Problem has beeen somewhat fixed by Removing the Auxillary lights from the front bumper. It seems to keep my coolant temps a little more stable when AC is on and also slightly lowered my IAT's. It hasn't been as hot as the few days when my car was overheating, but i truly believe removing the AUX lights helped somewhat. Thanks
