Needs more information. What do you mean by "what's going on in this P28"?

It is used on lsv in an ek. Was told it is "street tuned". Trying to get info on what I am starting with with whats in the car.

So are you asking what fuel/ignition maps are on the chips then? If so, that's a question someone with physical access to the chips and a reader is going to be able to answer.

I can answer your question right now. NO, it is not street tuned. In fact it is not tuned at all. You have a basemap chip, or a universal map of some sort on the chip. which is definitely not a tune.
How can I tell? The CN2 port is empty, nothing installed. that is the datalog port that is REQUIRED for tuning in any form. seeing it empty proves it's never been datalogged ever, and therefore never tuned in any shape form or fashion.
Also, j12 resistor is still intact. it needs to be removed in order to datalog as well.

What you have is a simple chipped ECU. The upside to it, about 99% of the work has been done to install hondata or demon

While what your guys saying is 100% accurate in the "real" tuning world, it's not necessarily accurate out in the actual world. I've seen more than a few setups come into our shop that have indeed been "tuned" to an extent by a low rent street tuner and not a single data log was done. It's rare, but there are people out there tuning off just a wideband and spark plug readings. Some do better jobs then others but they are out there. You really can't know if a car is in a proper state of tune without throwing it on the dyno, reading AFRs, timing etc and seeing if it's accurate and making the most power it can. What you guys pointed out is definitely a good sign that it is a generic chip and NOT a real tune, but that isn't exact science because someone very well COULD have put in the time to dial in a simple bolt on setup just by burning chips and making changes. It's not ideal but ive seen it fairly often.
