SAFC to tune my B20 swap?
First off, would tuning it get me ony more power, since it is a bigger engine running on a fuel map for a 1.8?
Ok so i have been having these bogging problems that come out of nowhere, so i finnaly gave up and took it to a shop, they tested everytihng and all the sensors are ok, they told me that since my ECU and injectors are set up for a 1.8 and its on a 2.0 that may be the problem, because my car works fine at WOT, but it bogs somtimes in low rpms and if not given WOT.
So i am wondering if a SAFC would be a good thing to add in and have it dyno tuned to get the bogging under control. What do you guys think?
Heres the thread on my bogging problem for those interesed

why not get a custom chiped ecu
or a tunable ecu program like urberdata, do a search u will find a ton off stuff about it
SAFC is a nice looking urberdata program witch wires up to the euc, and has far less options for alot more.

Just my $.02:
I did a B20 swap and ran a 96 LS ecu in a 97 civic. We came up with code 43 and when we checked it with a scanner it was code 43 lean, there are 2 code 43s one rich and one lean. So what we did was to replace the 240cc injectors with 97+Prelude injectors they are rated at about 275~290cc (sources don't agree) and that solved the problem. The long term fuel trim was a mere 0.8% and checking the stock O2 sensor with the scanner yielded a slightly rich mixture at WOT, it was about .93 volts.

Re: SAFC to tune my B20 swap? (Octoman)
How do you know if its lean or rich, my ECU is a 91 LS ecu, so it probably doesnt have the codes for rish and lean mixtures...just a regular 43.
The plugs are black, except for the peice of metal that comes out over the electrode tip was kinda white...so i dont know if thats normal or lean...
Ill have to get some pics up, but im thinkin injectors may have somthing to do with it, but i think im getting lower MPG than i did before the problem, so fuel starvation doesnt come to mind as the problem...i dont know though, im still testing :D
