Does anyone have an ECU file that starts well, idles well and doesn't have lean tip in that is running Deatchwerks 600's? I want to drop it in and at least see if it cures my idle and tip in problem.

It dies on me so many times today it was embarrasing. Won't run with AC on. I've tried and tried but I don't think that I have something fundamental that is preventing any further progress.

Like the Dead Time Correction. I know mine is wrong but I haven't the slightest idea what is right. Matt looked at Propsero's and immediately knew it was wrong.

Please help and me love you long time. Travis? Any help for your first guinea pig?

I also have no Idea what my dead times are supposed to be
I'm going to try to get them from deatchwerks but dont know if they'll play ball

*edit: as far as idle and all that, I mimicked y8's settings while keeping my fuel map and car is SOO much better its crazy. Night and day difference. Before idle was completely fucked, and it died on me and what not. Now its running like a champ. Check out his settings and go from there is what I'd suggest.

I have rx7 550 low ohms and I also have no clue what my dead times are. My ecu file originated from stein's so I'm assuming my **** is wrong as well.

Ahh, maybe I can help with this one... ECU file attached as I took some time today to add the values into the dead time correction. I suspect that this could have been my problem all along and that my injector that I thought was damaged could actually just been malprogrammed (sp) because the wrong values were in the field. Not that I am complaining.... there are just soo many values to deal with and this one seems to have slipped by.

Anyhow, give this a shot and let's see what happens. I will try to get this rolling as soon as my injectors come back from the shop. Excited as hell to see what will happen!

my current map

Stein

iTrader: (46)

For sure. Mine was supplied in the original base map way back in the beginning of time for that area so I don't know where it came from. Australia I guess.

I'm totally willing to blow away my whole map and all the tuning that I have done on this map so far to start with a clean slate. I think that I am continuing to mask inherent problems.

Prospero

I posted a map a few moments ago, the idle and corrections tabs were copied from Vlad's posting. I assume that they are based off of Y8S but don't know for sure. Tho thinking about what the dead time values are controlling it makes sense that our maps and fueling were all sorts of fucked since this really is controlling the injectors. Glad that Y8S pointed this out since we otherwise would have been chasing ghosts into the abyss!

Props to Y8S for pointing this one out and hope collectively we will make one good master map!

Cheers,
Prospero

Prospero, where did you get those values? They are way higher than y8s's for example. Like three times as high across the board. I'm not saying they are wrong but seemed way up there.

Prospero

They came from Travis's second post with the excel spreadsheet. I plugged them in based on voltage and went table for table. The lowest voltages did not take the full numbers... I tried to input the decimal but when I applied them it all reverted to 0...

Nvm, I found my **** here. Injector-Rehab - Fuel injector cleaning, flow testing, and complete blueprinting service.

Needless to say, mine was WAYYYY off.

Stein

That's what I was wondering. I looked at the spreadsheet and didn't figure they were direct input values due to the fact that they were so high. I'll try it and see.

Prospero

Ooooooohhhh, please....please lemme know how it works for you! I really hope this is the resolution to my high boost fueling issues and hopefully also a relation to my shitty idle. Vlad's description was spot on to what I have going on too!

Just got done watching "knowing" and I figure that the figures travis posed will predict the cure to our problems.... **** or is it the end of the world (EE)

Time for bed!

So how do dead times being off affect overall fueling. My deadtimes were off considerably. Like 14v was 1.5 and in reality its like 0.64. Would afr targets still compensate my map? Would the deadtime being input too high cause higher fuel consumption?

good article that explains it:
Yaw Power Products / Injector Dead Times Explained

The deatschwerks injectors do in fact have high dead times from what I remember travis learning.

That was one of the dumbest movies I've ever seen

TravisR

Yea somehow those got into the NB and NBB maps, while the NA maps had the right dead times.

In reality it may not effect much at all because the voltage shouldn't fluctuate that much, and cranking fuel does not get trimmed by injector dead time. Expect to do a little retuning though.

Prospero

I'm still waiting on injectors... but wondering if the dead time corrections made a difference for anyone?

Just burning with desire to know!

Oh and how about the new firmware? Anyone have any comments about it? So far it looks good with the little bit of playing I have done tonight!

I changed my map but I'm not going to be driving my car until the end of next week. The turbine flange on my manifold warped a little. 0.015" gap is causing me not to spool until 4400rpm. A full 1krpm later that pre-leak. I'm going to take it off on Sat and resurface it on my bench sander. On Sun I plan to test out the updated opening times.

You still need a map stein? I didn't notice your edit

Stein

iTrader: (46)

Yes please. My **** doesn't idle, still has lean tip in and about pukes on itself if I turn on the AC. Other than that, it runs great off idle. Well, except for that part where you are going from off throttle to on throttle going down the road and it goes full lean every time you touch the gas.
