Hondata

Different question since this thread is already here... Is it possible to calibrate the tach output? My stock EF tach is incorrect, or at least it does not agree with the Hondata. I haven't figured out how much the scale is off exactly.

Alright then. Thanks again!

Ok, thanks. Can you explain why it might be bad to use the IGP source?

My question is can I use the switched power from the ecu to power both sides of the relay when adding an IAB solenoid to a p28 ecu? Or should I use a power circuit that's entirely separate ...

It stays very rich after it's warmed up too. I'll have to make another log.

The very first log I uploaded is the rich one... It's not much, just sitting in the driveway but somebody might be able to spot anything screwy or give me any suggestions... It's not a tuning problem I don't think, just MAP or fuel pressure or something is acting up. The tuning was shaping up great ...

LSvtec swap with gsr head, 240cc injectors, stock IM, stock exhaust manifold. IAB is intact, but not hooked up yet; butterflies are always open. All tuning and datalogging is in open loop, including the time it's been acting up.

I forgot to include the calibration ...

Can anybody spot anything goofy in this log? I was getting really good results tuning my low speed fuel tables with my Innovate MTX-L, and one day it started running super rich when I hadn't changed anything... I can post a slightly outdated log of before if that would help.

Any ideas as to what ...
