This thread is not intended to replace the Official tuning thread but rather I would like some feedback on my understanding and procedure before I post in there.
A little bit of background info. I have an 80 series 1HD-FT with the A442F Automatic transmission with 333,333 klms on the clock. I have previously tuned the pump and boost compensator with good results but now I have a new turbo on its way and I thought this was a good time to put some of my thoughts and understanding down in words before I embark on the tuning when the new turbo is on. With all the reading I have done with regards to tuning I have not seen a written step by step tuning procedure until recently.
I plan to start tuning from step one and my intention is to get the best tune for my setup. My perception of the best tune may be different to others but I want a clean, safe tune with optimal boost response without smoke.
I have on board boost (both pre and post intercooler) pre turbo EGT and AFR gauges plus the ability to measure pre and post intercooler temperatures and exhaust manifold pressure.
Anyway, the next post will contain a tuning procedure that I have not yet used. I say again this is a theoretical procedure at this stage. I would like some feedback and thoughts from the wise folk here before my new turbo is installed and I begin tuning.
