Chrisc3 Test Log

Website, it will graph your CSV files, fast to make an account. But you have a few logs but just to show you I did one as a test. Be best if you could upload them all or which one has corrections and air intake temps?

How hot was it out when you did these runs?

Yeah that's better. It looks like that's mainly just a mid rpm cruise. I see it spikes to like 5k rpms briefly. Air temps look good but for these analysis for performance mods its best to do a full WOT 3rd - 4th gear pull w/o DTC, safely, to see how it handles under load for a few seconds. I am not an expert so idk how to interpret methanol values. Someone else can chime in on that.

Yeah I mean your IAT's look super low. Its relative to ambient tempersture , Idk how hot is it over there. I have an upgraded fmic and I never get temps that low. However I'm in AZ where the temps are > 100 degrees fahrenheit my IAT's float in the 120 range.

I have upgraded intercooler but i still have the logs from last month with e85 and boy was i was toppin off at 150+ iat. When i did my very firdt run and looked at the graph i was thinking the meth was going to help it from climbing but i didnt expect it to actualy drop temps this much. Its pretty warm here about 90 fahrenheit now but dam 100+ were your at is pretty darn hot.

The only other thing I would look for is how your timing on each cylinder is? Is there anything similar in your logging?

Actually for the JB (is that what you have?) I believe there is a new update from a week or so ago that let's you monitor all cylinders. If not I think it only looks at cyl 1.
