setup is 99 Y7 Greddy 19t @7-8psi intercooled RC 310cc's

Fuel:


Ignition:


yes there are only low cam maps....non-VTEC!!!


Just wondering what you guys think...it's only a basemap that came with the ECU (was made for my setup though) but the car runs
great...you see any problems? Maybe the timing is too conservative?


Bonus random pic:

done

Timing seems a bit high in the vaccum.

Also timing seems high past 5.8k

yeah, I dont like the 4 degree jump from 5600-6500, the fuel seems good until you go from 586 to 496 from 5600-6500 again. It is not to likely you will see those cells but I would change them just in case.

thanks guys...it's only a basemap that was made without the tuner ever seeing the car, got to get to the dyno ASAP. Still this basemap is 10000000000000 times better than the Emanage I was using before. I've only been revving it to 5K max until it sees a dyno, I just really love the torque these SOHC's make from 3K to 5K.


Kill list so far on basemap:
-auto G35, I pulled 2 cars at the top of 3rd not taking it to redline
-00 or so Porsche Boxster, Kept even with it from 2nd gear till 4th

alot of people are sleepin on the amount of push these SOHC's can make with stock internals.

SOHCD16y8

glad to here your enjoying it, just wait till you get more boost and tuned to redline.

I don't see what the problem with that decrese in fuel - its a non-vtec sohc with a crappy (for high-rpm whp), meaning it uses less fuel due to volumentric ineffiency. If you look at mu current vtec-low map, it peaks at 3.4k and drops - 13:1 WOT through that whole map till vtec. I'm guessing it increases near redline again as a precaucion from the basemap creator.

SOHCD16y8

You run 13:1 at WOT!!! thats pretty risky, im assuming your boosted.

HiProfile

not yet. The only time it sees 'boost' is if it ever backfires somehow

What I'm getting at is that my values drop towards the end of the low map, i.e. when the low cam starts losing power.

boosted k20

like people said, lower the timing from the 6.5K and 7.9K by 4 degrees.

get on a dyno to log those a/f. dont be boost n too much on a basemap

Yes but he only has a low cam, and although he may be losing he power, he is still boosted and at the higher rpm is much more prone to detonation then bieng N/a, which is why it is important to have plenty of fuel and good timing, yes it may end up like that after it is tuned with a wideband but , for a basemap you really dont want to risk that.

I am not sure, but did I make this basemap? I don't remember. But if you look at any single non vtec, where is the max tq at? That is why it has an increase in the upper RPMs of ignition timing, but like was mentioned, it should be retarded a little bit more past 5.6k, not sure why there is a 4 degree jump, i would knock it down to like a 1.5 degree jump.

Also on a single non-vtec, the timing maps in vacuum are a lot higher than a GSR or other motors. Also it might use a little bit more retard because of it being OBD2. But let your tuner decide on that one.

Good luck on your tuning man!

Needing less fuel in the higher rpms on a Y7 is about right. I just pulled up Ari's tune from back in March, only Y7 I've ever touched... after 5500 I started pulling fuel. Not quite as much as in diet rite's basemap, and converting the 450cc tune for 310's it looks like she'd be a bit lean in boost, so getting tuned before boosting is definitely in order.

As for the ignition, high part throttle ignition rocks your socks... I'm @ 56 degrees for my D15B7 and get 40 mph on flatland cruise... and you get a nice little flash of ignition timing everytime you jog your TPS to add to the map's base figure. As to the ignition in the boost event, it is a good safe start point. Even the high rpm peak at 6500 is still in the neighborhood of 1 deg/psi. Being a Y7/Y8 head, you might want less than that, though. Just like this guy said:

All engines are most prone to detonation at their torque peak. High rpm boosting is a lot safer and easier to manage than long drawn out midrange pulls, where you scrape past torque peak.

I'm curious about the painting. Who's the artist?

Exactly.

This basemap was actually on my sister's tuned greddy setup. Yes my sister drives a turboed hatch.

I added about 12 percent to the map, giving it about a point richer in boost and also retarded the timing from where her's was at. I did this because it was a basemap, and it should be good enough to get him to the tuner. Enough said really. With a basemap you really boost at your own risk, but that is my explanation for the map being the way it is.

yup it's yours, works great!!!

Dammit I thought this was the case....I guess it's like anything in life , it's the most dangerous when it's the most fun (torque peak)

and long drawn out pulls are what this car does with this DX trans.....I dunno If I ever want to upgrade to an EX trans because I like being able to cruise at 75 at barely 3K RPM worth the trade off for me right now. 1st 2nd and 3rd are pretty nice but 4th and 5th are MPG gears. Anyone know if they only changed the final drive on the EX? Or did they change 3rd-5th and the final drive?

Joseph Davis

Nah, hp peak is where the fun is on a 4 cylinder. D-series not being as high rpm oriented, you need to have safe usable power in the torque peak area, but your best power is still going to occur above tq peak.
