Hondata

07 Honda civic Si
CT-E Supercharger kit, 3.6 inch pulley, modified stock injectors, Vibrant Header w/ High-flow Cat, CT-E intake (approx 20k miles on SC)
Flashpro Serial Number: FP-SI-US-10164

History: Originally ran the stage 1 flash, when I read that the injectors were running at 100% duty cycles in high temperature climates, and the stage 1 tune provided with FP beta version 9, I did some data logging to confirm. Sure enough injectors were at 100% duty cycle. I then decided to upload the CT Stage I tune to my ECU and noticed a number of different problems. 1, I was using a dashhawk to monitor my Car. My Dashhawk can no longer pick up boost in PSI, and in KPa it measures everything in (-) pressure terms, I also noticed that when in boost I started to run lean (13:1 and higher).

Next, I decided due to the lean condition I am having I would get some modified injectors and upgrade to the stage 2 tune. The same issues as stated above also appear, Dashawk no longer reads MAP sensor correctly, etc. However, the Lean condition at this point increased substantially (see attached Data log). I proceeded to attempt to add fuel to the particular areas involved with no luck in improving this performance.

Problem: I am not sure. Is it my injectors, fuel pump, tune? A little advice or help would be appreciated. Attached is the data log from a freeway acceleration I was running. If it's my fuel pump, why would I begin to richen back up as the RPM's climb. It should also be noted that the lean condition is very prominent in the 3,000 to 4,500 rpm range.

Things I know: I need a wideband guage (sold it when I realized my dashawk read AFR), Boost Guage is now apparently necessary, and I can't drive the car anymore. Looking at the plugs, they do not look fouled, so not sure.

@ hondata

I'm in for asnwers too having the same issues - the daskhawk cuz i don't have one.

The word around is that these 2 base map are NOT correct. I think hondata needs to do some tweeking to the CT-e base maps ASAP. Alot of ppl are having these issues, lets get it fix before engines get fu*k rrrrghhh. I have been wrapping my head around this trying to fix it

The DashHawk does not work with the race calibrations as it uses different datalogging protocals.

There is a variation in FP as a result of crushing the regulator resulting in different fuel pressures and AF ratios.

Make sure all tables are checked when editing and try the following on the High cam Fuel tables:
add 10% to all points from 0-3500 RPM
add 8% at 4000 RPM
add 6% to 4500
5% to 5000
4% to 5250
3% to 5500
2% to 5750
1% to 6000

Thank you, and could you add this to the CT-e base maps, so when downloading FlashPro it will be included to help the noobs.

I used those numbers recommended, with slightly better results but not quite there. See the attached data log. The point in question is from 1:15 to 1:36. Another individual pointed out that he had this same problem and his O2 sensor had gone bad. I will attempt to replace this and see what happens in the next couple of days.

Thanks

Ok, i replaced the A/F sensor, and had a little bit better luck but still running a bit lean. I'll adjust per Punkster's request before and try again.

Hey Prizm, what was the outcome to this?

Well,

I replaced the A/F sensor, no luck in the base map being accurate. i was running really lean, like 15:1 under boost. So, I added RC 650CC injectors and a walbro fuel pump with no luck. So, I adjusted the fuel maps to get rid of the lean issues and I'm just tweaking them now. I have a new Fuel Pressure Regulator and I'm debating putting it in without crushing it to see what this will do. I'd have to start from scratch with a tune though.

Make sure you have the map relocator installed correctly so that the MAP sensor can read boost and not just vacuum.

Ok, I'm going to look like at idiot here but... what? I haven't touched the MAP sensor since the SC was put on about 20k ago. Ran fine with the originaly stage 1 tune and I am seeing boost in my data logs. As far as I know it's located correctly. Can you explain how it could be done incorrectly and not read boost?
