I bought a RAMJet OTR. A wideband.... dialed it all in...... for months now i've been trying to solve a very odd leaning out issue which is primarily when the car is hot and off throttle....... it leans out to til 25+ ...... MAF or VE ..... or Transient compensation never fixed it..
Anyway ...... So I have a question as I think I found the problem. I had a transmission cooler where the OTR now is but.... I moved it to the lower part of the front of the bay....... but infront of the OTR filter.... is a loop of metal pipes which run down to the transmission cooler.
My thoughts are...... The heat of those pipes sitting directly infront of the OTR is throwing the maf out off throttle....
What do you guys recon? .... there's quite a bunch of bent loopy pipes there, I will take a photo when I get home.... I just want to confirm this before I go about fixing it.....
air/fuel ratio's are right etc........ I looked at other peoples tunes with OTR's they just have done maf etc...... like me, i'm the only one with this problem but i'm the only one with these stupid transmission cooler pipes right infront of it.....
You guys recon thats my issue?
