Hondata

Hi Gents,
I have been building my turbo d16y7 (tt rods, wisecos, topmounted GT2871R with T3/T04 housings, RC 750s, Tial 38mm, 3" side exit etc etc) for 4 years and finally got it on the road with the turbo/injectors/ecu fitted at the weekend. :D

I could not find anyone who would charge me less than ~$200 an hour to map it so thought I would give it a go myself. It seems a lot easier than I thought once I did some research! I am also now thinking about becoming a Hondata S300 mapper for my area as I am in a huge honda club and the only 2 "Approved" hondata mappers in the UK focus on Kpro.

Anyway - I used a basemap from the stock P28, and pulled 4 degrees of timing across the board (y7 base timing at 12 deg) and 1 degree per PSI in the boost columns.

I am pretty happy with the fuelling, timing cannot be that far off IMO.....but not sure! I will worry more when I turn the boost up!

Can someone look at the attached and offer any advice? I know TPS is not quite right but as good as I can get until I adjust the throttle cable length. Also my PLX is using the 0.35v offset and not going above or below certain reading due to the resistors. Let me know if you want more info, I already have lots of datalogs including one that goes to 143mph :)

Anything else look untoward?

no replies? you have to be logged in to see the images :)

im confused why your AF is reading .81.. the fuel looks smooth, but you need to change the settings on your AF from.7-1.7. to 10-20 on your graphs.. Click on AF on the sensors tab, and youll see on the bottom, Display Min, Display max. change those to 10 and 20.

they are lambda values,maybe he prefers to think in those values instead of AF.
OP u should post the cal & data files rather than screenshots,gives a lot more info to anyone that can advise u on a boosted D.

why dont u adjust your TPS electronically under the TPS tab,instaed of going to trouble of changing cable lengths?

whant to share your map?

my email is khmoe@online.no if you please :)

I'll be keeping my eyes on this thread..........yea i'm a noob & i'm hoping this topic could branch of into something informative.

I think I looks good but I would put more fuel in on the top side from like 4000 up. From what I see in the graph your only making to 39% duty on the injectors. Turbo Like Gas....

Hello guys,
This car is still running, I continued to fine tune the map from the above until about July 2010 when I had an accident with the bonnet flying open. Since re-shelled the car and did some new mods (mainly improvements to the tuck/plumbing etc)
Stupidly I lost the map on my old laptop and managed to corrupt the one on the ECU, so I am so happy to have this here to re-start from!
Cheers
