Datalogging

[DZ SHO]

In regards to datalogging, is there any additional power left if I were to datalog and send back to Gearhead? I just loaded the tune and thought it was a done deal...

Did you recieve an AO tune or did you get a dedicated octane tune? I have over 10 revisions on my E30 tune. Each time something was changed and it became better and more refined.

10!, that is what I'd call fine-tuning. Did you have to pay extra for that many revisions?

I didn't. I worked with Brad and started extrapolating extreme heat data. He noted my SHO had the highest IAT2 data he had ever seen. Through each revision along with each modification (DP's, IC, ect) we learned and help build his data base. Also, I am 100% not afraid to tell him to SEND IT. So I guess I was a special case.

I opted for the AO tune.

That is basically Matt's plug and play tune. I don't think it would hurt to ask if he would like to see a datalog it. Most tuners like to see how things are going.

Agreed, if he saw room for improvement I'm sure he would send an updated file.

Corrected my statement.

I learn something new everyday. So tip is at the throttle inlet, and manifold absolute is the 3 bar on top of the manifold correct?

yep! I actually wish there was a pre-intercooler sensor to measure pressure drop, but no such luck

The drop in that short distance is dramatic. It because of the "high" ram intake design?

Sent some logs to Torrie because my car feels essentially stock right now. He says my KR is extremely high. So I am turning my water\meth back on and going to a local station that sells race gas and E100. Maybe I can remedy this KR issue.

I just sent him another log this morning, (no response yet so he must have today off lol) still having inconsistences in power. I see my kr is down to 1-1.75 now from 3-3.5 but feels just above stock. Hopefully my next revision will take care of this issue.

I fixed my KR. All zero or negative. I blended 3 gal of E100 with 91 octane from a good station (RS fuels). By the way, 93 is really cheap right now as well.

I was wondering if you can watch your knock retard over time while trying different gas stations to see which gas brand is better at 93? I may start doing it if i remember too.

KR response is pretty quick after you fill up. So I would imagine if you logged a pull after filling up at each station than compared KR you could get a decent understanding of good and bad places to fill up.

I’ve been doing exactly that as top tier gas is hard to find by me. Every big name station has been bought up by discount open market stations. Costco so far, which is top tier has proven the best thus far.

be careful doing that and don't tune for it unless you plan to run it all the time.
