Tuning help for S1 with catless midpipe

[spacecaptainsteve]

Hello all,
I've got a series 1 (6 port manual) with a catless BHR resonated midpipe and no other performance mods. I made my own tune only to increase oil injection rates and adjust the temps when the fans kick in, but I was wondering if there was a good resource available for tuning. The ecu seems to do a good job of automatically compensating for the change, but frankly I have no idea what I'm doing. I was going to leave it as-is, but if there's more power or reliability to be had I'd like to pursue that. If someone can point me in the direction of guides / tutorial that would be appreciated.

Bump.. since this post I've installed BHR's ignition and put in a K&N drop in panel.

I see people citing 5ms dwell times for those coils but haven't implemented that yet.

I'll probably spend time looking at the premade tunes, but none of them really match what my car has. I understand that its very unlikely any of these tunes would be causing damage as the ECU is pretty safe. But most of these premade tunes seem to either be "high flow cat + gizmos" or "midpipe and matching exhaust bits + revi intake" etc . I don't have a catback (yet) or headers, just midpipe. And the K&N isn't nearly as good as the racing beat. I guess I have reservations about using a premade tune for a car with better (or worse) breathing.

You don't really have anything that requires tuning.
On their own, you don't need to change anything for a catless midpipe or for the D585 coils (BHR v1) and the BHR v2 don't require dwell modifications as well.

Which version do you have BTW you didn't say?

What you have is the ability (or room) to make changes say for example to the AFR's without worrying about killing your catalytic.
Or changing the DWELL map in order to produce a better result.

I don't ever recall seeing a canned tune for a K&N panel filter but maybe there is one out there.
Intake modifications IMO are unique per car and need to be handled that way for the Maf scaling so I don't like the canned tunes that say this is what you should use for this or that intake. Also I've noticed changes to the first two cells which I had bad experiences with modifying.

The canned tunes also have slight modifications to other tables that are useful, and likely usable on a totally stock RX8.

Download some of the canned tunes and compare them to your stock tune.
