I've had this car since around feb. and have been watching the IAT1 and 2 they were ridiculous and I found a bad IC pump, replaced that obviously thinking that was the largest issue it has helped but hasn't solved my issue. I was seeing up to 180 sitting and driving nothing lower than 13x many times instantly climbing to 160 at a stop sign.

I now have an option b and have bleed the hell out of, water/methanol, wideband, Badmab mani, zzp dp and 2.5 exhaust all the way back with 2.7 pulley with 60's and zzp s3 HE with stock still being utilized.

My issue now is that I can cruise around in 60* weather and only see around 100 and 80* around 110, I know that's not too bad at all but even with the w/m spraying iat2 barely drops 2 to 4 * while spraying and instantly starts climbing I can see about 145 by end of 2nd and close to 150/155 by third if not more I usually stop pulling as soon as I see it close to the 140's. I can keep driving normal and it will return around the normal.

I know something is up but I'm not sure what exactly is going on because the tuner can't get but maybe 3* advancement before it starts having too much kr honestly it's like I'm not even running the water/methanol but I know it's spraying I have the AEM progressive kit with the led that lights up as it's spraying and I can see it on the wideband kick in as well.

Any one have any ideas where I should be looking for the issue? My previous lsj with same mods could see 15-20* drop atleast with w/m and never see those temps for the iat2's.

 

Your laminova coils could need a good cleaning. After you changed the pump did you make sure the new one is working?

 

I was wondering about the laminova cores but wasn't sure if that could be an issue or not as far as the IC pump it's definitely working

 

Make sure the cores are lined up with the slots in the manifold also

 

I'm assuming to do that you have to remove the LIC to make sure they are aligned. I will double check that I had thought about replacing it with one that had newer cores or even a single pass that some make but I haven't had the extra since we just moved. The previous owner rebuilt the engine but that's not to say the interxooler system was looked at or not done put back together correctly since I've found a few minor issues in the months I've owned it.

 

Yeah you gotta remove it an take the end plate off slide em out an see if they are aligned

 

Did you make sure to hook the IC pump back up correctly? In regards to the flow direction?

 

Yes I did lol I know some people have over looked that but I tried to make sure it wasn't anything redundant or a stupid overlooked issue like the pump being hooked up backwards. I double checked the flow when I installed the option b i made, for a part of it I used clear high temperature hose so I can see air and flow. I'm strongly starting to suspect the cores either bad or dirty even today 85* I was able to cruise and keep around 113 to 115 at times running the ac. But on my way home from work at 8 am it was maybe high 60's low 70's crusing was 100 2nd gear pull and barely blipped third and seen 152 already.

As soon as I can pull that off i'll report back other than checking for ideas and replies. I know the front mount's fins are bent from the previous owner not having a screen but I don't see that being the issue since I barely drop 4* while spraying the w/m before it climbs to the sky and produce kr that limits the tuners timing advancement.
