Kamotors E30-Turbo to ITB M20

[kamotors]

Looked into running ITB mode but it seems to use speed density at WOT still and just alpha N for low load, which is not really my issue, my map signal is very stable at low load.My least consistent signal is actually at WOT, it bounces from 81kpa to 87kpa( i live at high elevation so I cant reach any more KPA)

I''ve read that adding check valves on the cylinders feeding my vacuum block can help smooth the signal or just adding a restrictor to the map signal line. I'm going to give a restrictor a try because I'm not getting consistent data from WOT pulls, one pull will run at like 12.2afr while others run at like 13.2. the only difference is usually air temp but even thats not differing much between pulls.

What's your AE tables look like? That map looks like AE might not even be enabled?

AE is enabled and 100% tps based only.


That tune is only my third revision so far from doing like 6 or 7 datalogs.

How do you read that table map

So here is how the speed density map looks, its working great for low load and rpm driving, great at WOT but the only place it has issues is high rpm low load driving like if your crusing around at 4krpms light throttle it runs rich and choppy.

coming from a few 20v 4age's with trumpets im used to seeing trumpet cars rev to 8k.. the 6-8K rev I see is what really makes the ITB setup from the noise alone. The point the setup comes alive

possibility of raising the rev limit and putting in some beefier rockers? at 6500 it looks like it wants to keep revving.

I'm revving out to 7300 now, video was still just on my turbo setups tune. I'll get another video once it's properly tuned I'm thinking of keeping it on speed density because I'm not really seeing any downsides. I have Accel enrichment 100% off of tps and everything else map sensor and it has great response and pulls nice as well as cruises nicely.

Sounds amazing. Do you think you'd ever sell the ITB tune through your website?

if I could get it perfect

Runs surprisingly well on speed density. Only has fueling issues on light throttle cruising. But I'll get it on alpha n soon. Spent all day building the exhaust.

why is the needle on the other side of the world? is it meant to be easier on the eye glancing?

moves into vision at redline doesnt go into my econo gauge anymore past 7k.

lol that tacho looks so good :)

r u going to get some roller rockers to rev that high?

I've been revving to 7300 for a few years now. No point going higher with current cam, or bottom end.
