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.:makeout: Travis? Any help for your first guinea pig? |
I also have no Idea what my dead times are supposed to be:mad:
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 shit is wrong as well.

How about putting this into inputtable values? Propsero's dead time was wrong because mine was wrong but we were running with what was supplied. Might be the issue that I have with the lean tip in but I don't know how to covert the supplied values to data that I need.
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! :) Cheers, Prospero Attachment 12902 |

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. |

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.

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.

Nvm, I found my shit here. Injector-Rehab - Fuel injector cleaning, flow testing, and complete blueprinting service.
Needless to say, mine was WAYYYY off. |

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...
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. |

Just got done watching "knowing" and I figure that the figures travis posed will predict the cure to our problems.... shit or is it the end of the world (EE) Time for bed! Cheers, Matt |
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. |

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. |
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! Cheers, Prospero |
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.
