Need an Emanage Guru for Turbo Tuning
Hey,
I know its not exactly the right place to post this but here I go: I have a 3SGE Toyota Altezza which I have just installed a TD04L-13T turbo onto, I have an emanage ultimate with map sensor for tuning, everything is installed but just need some help with the base map to get it going, I dont have access to a dyno or wideband at the moment, I've been looking long and hard at some Turbo Miata maps and was thinking about the possibility of getting away with using one. I found a really good one which had timing and fuel adjustments based on boost pressure, Not sure how suitable this would be as my engine is 2.0L and I think the map is from a 1.6 or 1.8 miata. What do you guys think? Reckon I could get away with the map, It beats the hacked up H22A turbo map I've been using :P Cheers, |
This thread will wither and die unless you tell people what part of Outer Tazmania you are living in.

Hey,
I'm living in Northland, New Zealand, Hope it helps, |
Olderguy, I just have to ask- was the Outer Tasmania remark just a total wag? Because that's a relatively close guess. :D
leideno, he's alluding to the fact that we like it when people put their location into their location field (see under my name?) and some info about their car into their sig. I can't provide you with a map to use, only to offer some advice. When I installed an EMU on my Miata several years ago, I was an early adopter. I didn't have anybody else's map to copy. I simply created one as a guess, starting with +10 at 0 PSI(relative) and scaling up to +80 or so at 15 PSI (relative). It was very rich and not even close to optimal, but it was enough to get me running so that I could use AutoTune to refinie it. This was done through several weeks of street driving, using the wideband sensor. I would not even dream of installing a complex aftermarket EFI system without a wideband sensor. |
It was a wag based on "cheers"

LOL Okay my bad...
Yea thats pretty similar to the map I have at the moment, here's the data: http://d.imagehost.org/0350/em2.jpg I am yet to take it for a test run and log with this map but it looks like it should be adding enough fuel/retarding enough ignition for me to get by, Going to purchase a A/F guage, aparently it works of the factory O2 sensor.. I have my doubts... |

Basically, you need one of these: http://aempower.com/ViewCategory.aspx?CategoryID=67 http://www.innovatemotorsports.com/x...cat=262&page=1 |
are you using stock injectors? well even if you do tell me you are i still would agree with Joe that a wideband is a must. don't waste your time without it. maybe you'll mess something up.

Yup I'm using the stock injectors which are rated at 365cc's
I've been told they run at around 90% duty cycle at 8 psi... With the map above I'm running at close to 100% duty cycle under full boost (9psi, 11psi spiking) and timing retarded 1 degree per psi so can I assume that there's adequate fuel being added if the injectors are nearly maxed? May not be the ideal a/f but it sure pulls hard, I took a look at the logs and noticed the knock sensor is reading out 7-10% knock. Its set to Resonant and normal frequency. I also noticed its only reading out knock when I come off the accelerator and the injectors are cut... http://img522.imageshack.us/img522/7321/emlogsm9.jpg |
