I recently purchased a Power FC for RX7Store.net. With it they included tuning for the particular mods I have. Has anyone else had their's tuned by RX7store, and if so, how did it turn out. The reason I'm asking is the last thing I want to do is blow my engine running too lean etc. Thanks for your help.

 

I didn't have him do a full tune, but Jason did give me a timing map.

I had a pretty good tune before just rich and stumbling on it's self at high rpm after the previous owner pulled the Jacobs ignition amp off. I bought the car and was able to clear it up with the HKS twin power. But I had Jason look at my timing maps just to be safe. He changed just a few cells in the leading and trailing timing at around 6000-8000 rpm. At that time I had the datalogit, wideband and was monitoring knock levels. He gave me more conservative timing numbers up there.

So I made the changes and logged numbers. I found that my knock levels were 5-10 lower then before up in the 6000-8000 range. I was hitting 30-40 and now I saw 20-30. So I kept his changes. Didn't notice or feel andy power changes, but I didn't expect to with that minor of a change.

This was all done over the phone with listed details of my mods. I've then later pulled fuel out a few areas to help the tone the richness back some.

Just be careful and take it slow, log and monitor everything you can.
