ECUflash CeddyMod v1 (EcuFlash)

[GSXeclipsePSI]

Ok went out and logged. My log data is in all the wrong cells after i added 2.7beta.... I had to cause the log file was empty every time and 2.7b lets you pick a output folder and it works fine. But now the data is all over 2 cells.

Anyone?

Which version of 2.7? I had the same issue with 2.7beta5 and I fixed it by reverting to 2.7beta3. There is a bug in certain versions (hence the "beta" part of the versioning). Happily, the final release of 2.7 should be out soon, a private beta for final testing has been released.

I got some footage today of 6k rev limit with -20 timing and 9.0afr anti-lag on @ 5500rpms (12psi) w/SCM6152e @ 19-20psi

I can't wait to antilag the shit out of my ebay turbo right before I pull it off.

Seemed a little slow out of the hole there.

2 things to say

Stock Tranny
6puck 2600

Im trying to be nice to it (kid of)

If not I would be at 7k popping it but I like to slip then pop the clutch. I am still getting use to the 6puck only 5 launch so far. My street disk was a little different and I had a 16g for 5yrs.

 

[Afroclipse]

you guys need a FAQ on that site or a intro page, I want to know whether it will work right with a 95 and if the ecuflash is for 95 or evo ecu's? after all that reading I still didn't get my answer.

 

[Ahnubus_29]

As it states on the very first page that this is for only the 98/99 eclipse/talon turbo ecu's, and you can swap one of those ecu's into your 95 turbo eclipse directly with some issues from the cas but ceddy has a fix for that. This has nothing to do with evo ecu's other then their helping ceddy with this project.

That sounded all douchebaggy

No it didn't at all.

You say you read everything through, but your question showed that you didn't read at all, or just didn't really pay good attention when you read.

There is a bug with the 10-bit ADC not updating properly, this effects SD calcs only. I have this fixed in version 1.95, it is now updated at 100 Hz.

There has been a change here on Tuners, that you are no longer allowed to edit old posts, so I can't edit the first post to add download links.

So new version downloads will be here -> http://ceddy.us/?page_id=16
(1.95 will be uploaded in a few hours.)

 

[GSXeclipsePSI]

Yes the 1.95 did correct my problems with SD tuning. My FP manifold just got here so I'm on hold for a few days, plus I'm waiting for my HD WG that's getting sent from PTE. So I have a few holdups again since nobody can get orders correct.

I have been playing with the idea for a single 3D VE table for Speed Density. Like the Evo guys have planned for SD 2.0 (kPa x RPM)

It wouldn't be hard to add, and would allow much higher resolution because of how the math is set up in the H8s. But a 3D table would take longer to set up.

I'll wait til I have more feed back from people using SD.

I seen the 3D map on there but didn't click on it figured you just added it and hadn't done any work on it yet since you didn't list it as a update.

I don't think it would be harder to get a base tune. Since you can adjust a whole row or column, you can still tune it like 2 2D maps at first. It's the fine tuning where the 3D map would shine. I think a couple more MAP points should be added to the VE map though. And the fuel and timing maps really should be RPM & KPa or PSI, instead of RPM & fake load like the Evo one is; it makes it a major pain to get your timing set where you want it at different boost levels. Especially since the 'load' value changes drastically when the VE maps are adjusted.

A setup like mine doesn't work good at all with 2 2D maps, since when I up the boost a lot, I have to retune my VE RPM map in the higher rpms quite a lot.

 

[VETTE_50_TH]

DAMN! You put down 460 torque on e85 on a 16g? GOOD GOD! Cant wait to finish my 20g then!

Switching the Fuel and Timing maps to a Boost Axis instead of Load isn't that hard. The only draw back is users will have to select scaling and enter the axis divisions themselves, since every MAP Sensor has a different scaling.

I'm liking the idea of a 3D VE table more, especially for resolution reasons. The H8s only have byte sized table lookups, so the MAP VE table which outputs "Load" only has a range of 0-255, that you have to balance between resolution and maximum Load. A 3D table would take that out of the picture and allow 1% VE resolution for MAP and RPM.

Well I'd gladly be the second person to try it if you give it a go. The SD you sent me was unsuccessful, I haven't given the new revision a try yet.

I wouldn't mind MAP based maps even when using the airflow sensor.

Is there any way to accuratly account for having a higher fuel pressure?

Adjust your injector size. If you google it, you'll find a calculator so you can figure out how much your injector size is changed with different pressure.

 

[m_0ney_pit]

is this a linear relation or somewhat quatratic with increasing pressure? Does injector deadtime effect this at different load levels?

reason: i use the 4g64 fpr which has a slightly higher base pressure. I'm not sure what the though process was going with a higher base pressure for the 4g64 but i figured id stick with it. I tryed using the 4g63t fpr (bolts right to the 4g64 fuel rail) and the exact dead time (RC550cc) and injector scaling and the car did not want to idle at all .

 

[steve]

The ECUs idea of injector size is the effective flow rate. Deadtime is effected by changes in fuel pressure in a minor way and can largely be ignored except in the extreme cases.

If you look at the RC Engineering site you see that the effective flow rate changes with the square root of the ratio between the old and new pressures.

Since this calculation is external to the ECU fuel calculations the ECU computation is linear based on air mass and target AFR.

 

[Ceddy]

I've use the 1G FPR(38 psi) and a AFPR at 43.5 psi and DeadTimes values came out exactly the same.

Be sure to reset the ecu when changing Injector Size or Base Fuel Pressure. If your Fuel Trims are maxed out from your old settings, the ecu will add/subtract fuel and car may not idle right even if your new settings are perfect.


Had time to test SD today, there is another fix needed.
Version 1.96 will be uploaded tonight -> http://ceddy.us/?page_id=16

 

[VETTE_50_TH]

You are using a 1g fuel pressure in your ecu then using an afpr to make it 43.5?

 

[GSXeclipsePSI]

Hey I got my my stuff to match close under 120 and didn't touch anything higher. I took the car to meet someone about hour away forgot I didn't do load above 120 and I was knocking when into boost above 13psi and my wideband was solid on 10.8 without any changes while on + pressure at all I know I have more changes to make but is the SD on cause the car drove smoother then it ever has off boost, I was in love.
