Hi question for Vishnu crew , I am about to purchase the alcohol injection and cant seem to run the 10 table map with alcohol control and run lean protection whatever I try my car seems to throw a lean condition on hard acceleration and during shifts so I am asking you guys if you can send me a V390 10 table map for 93 oct. or if you guys wont too see my map that I'm trying too run I can post it here thanks .

 

What exactly do you mean by "throwing a lean condition?"

 

It studers violently on wot and the best I can explain is when I go wot till 7000rpm let off throttle shift back on throttle it hits I think it is a lean condition

 

I would imagine that it is the lean protect. Zero out the table for now, and let us work on it a bit more.

 

Ok thanks Dustin and please let me know when you find the solution .

 

We already found it. It's going to require a lean run condition of a finite length of time. Perhaps .25 seconds. Just something longer than what it is now (instantaneous). This will keep it from being falsely triggered while still protecting the engine. The software engineers and I are going to work on it during SEMA week (1st week of Nov). Coming soon....

will it help if you set the LM Programmer to average samples over a period of time vs instantenious readout?

 

It could help but at the cost of response time for normal SMART fuel adjustments. The whole idea is to make it as real-time as possible. That is first priority. We would not want the leanrun protect feature to interfere with that

I tried that and not only didn't it work, it negatively affects the performance of the SMART fuel system (as cited by Shiv.) Suppressing the lean run detection for a period of time is really different than integrating up a number of samples. I believe this is because the change in AFR is rather large during a shift.
