There is certainly an ignition table in there somewhere, there is one in the M3.3.1 which carried over a lot of the tables from the non vanos ECU. Think it is a 5x1 table, you will see it in the latest 506 ECU XDF. you're certainly right, I didn not search for ignition relative table for the moment...

Hi all, After tuning with success my new alpha/n table, it seems that I have a light increase of AFRs when the temperature drops. So i need to adjust IAT correction. I found 5 tables that I think are IAT related (descriptor D0). http://i346.photobucket.com/albums/p403/Evilt16/IAT%20maps_zpslgjviu4f....

As promised, here is how to extend the size of an existing table. (In my case that was for the "maf limp mode" table aka alpha-n. For that you need to fully understand how descriptors and headers of a table are working. first here is the "table list" in a 403 DME in hex code: htt...

Evil

Hurrah it works!!!!!!! So as I Said the new adress in the "table list" MUST be at the exact same place than the old one. Now all cells are traced, at all throttle positions and rpm in the new 16x16 table. Will made a better explanation this week with screenshots of what I did. Now I have t...

Evil

i did a first try without success, the car starts but the new table is not recog,nized so stalls as I press throttle.
I've put the new adress in the table list in order, maybe it is the problem, I will try again by writing the new adress at the same place that the old one was in the list.

Evil

I think I found it! The table begins in 78D0, 100x1 in 16bit, lsb first. Just replace "E" by "6" and "F" by "7" at the beginning of each "data" adress and here we go! I.e.: EEFC = 6EFC. I will try in the next few days to create a 16x16 table with res...

Evil

You should have this map, she is at the end of tables list in the xdf, "maf related limp mode map".

Evil

Can someone confirm that D0 is IAT descriptor for a 403? I need to adjust a little the IAT compensation. I found several tables with this descriptor but I'd like To be sure these are the good ones.

Evil

I have a 404 bin and the table seems To start in D040, am I right? Just To be sure I have understand ðŸ˜„

Evil

That's correct, 402/403 are 32bit and 404/405 64bit.

Evil

I did the same things last week but I found nothing too, the funny fact is that I was searching about wot fuel table like you did ðŸ˜„

Evil

Yeah thats what I found too after calculating.
In some cells i had To enlean for about 7-8% but I think my alpha n table need again some fine adjustments

Evil

You're right about extending the limp mode table, thats exactly what I want To do. I've done another thread about it to make it easy To ses for other people. I have some photos of the setup i will post them today. I polished the manifold up To 400, maybe its too much as you say. But the bignproblem ...

Evil

Hi Hairyscreech, You're absolutely right, there is a table in the code who tells all the tables adresses, but I couldnt find it, I dont know how adresses are. A 16x16 table would be more than Perfect, the original alpha n table is 7x6. With that I could tune perfectly at low loads with ITBs and have...

Evil

Hi Aboutton , I'm using 403 dme ðŸ˜‰

Evil

Hi guys Did someone ever experienced extending tables size? I tried with success To rescale rpm axis on WOT tables up to 7000rpm, now I would like to extend TPS and RPM axis on the alpha-n table (maf limp mode) To have a better definition on low throttle opening. It seems that it needs To modify som...

Evil

Normally it's the same adress for 405 and 403 : 6F71. Anyway, if you are using m50 injectors you dont need To touch this table. What has been rescaled exactly in your bin? If you are using everything from the m50 (sensors, maf, injectors...), your fueling should be not so bad even on a m20, load cal...

Evil

Its not the good table, this one is a PW correction from IAT and another value that I dont know the descriptor. I dis the same mistake by thinking it was latency correction but could not obtain any good effect. The injector latency correction table is 5x1 and is only voltage dependant. What dme are ...

Evil

Not sure but I think you'll effectively need a speed signal with 413 dme. I think that the speed signal for dme comes from the original dashboard, I dont know if the signal from the speed sensor is modified by the dashboard and then ditribued To dme, or if it's raw signal. Some guys used To split th...

Evil

Hi, I think that the 413 red label XDF will allow you To tune everything you need. Checksum will be updated automatically when you save your changes. Tuning will be easier by using an Ostrich 2.0, and then you can burn your .bin in a chip when tuning is ok. If you run no MAF tuning can be a little h...

Evil

After a bit of reflexion I think I have 2 problems that cause my lack of acceleration enrichment and also deccel enleanment: -my "manifold " between head and throttle bodies is stainless steel, and I think it involves condensation because he's always cold when engine is hot. -injectors are...

After many research I didnt found dead time value of my injectors. I have tried To adjust Injector constant and dead time but with no satisfying results... ls the injector constant just a factor, or is there an "interpretation" To read the value? In the original bin the value is 54953 . Or...

Evil

No problem hairyscreech ðŸ˜‰ Now its clear: higher the value = higher the enrichment. This confirms there is a problem ðŸ˜… with all values at 255 enrichment is not better... I'll check if I dont have fuel pressure problems, I dont think because my fuel pump is a 255l/h and its far enough for 270cc ...

Evil

For thÃ© 270cc injectors: there is no ref on them, they are from the gsxr, I'll search more To see if I find their latency.

Evil

Thanks for thÃ© explanation, I knew the principe about accel enrichment but the matter was I thought I had To increase values to enrich more. I have tried by lowering and its better but there's still a "lean hole". The enrichment seems To be "retarded": when I Press throttle it g...

Evil

Yes 270cc are a bit too much, but I couldnt use the m50 one because I run e85 now . I tried To adjust the latency but I dont know what need these injectors, it seems To be better with higher values. I will try more on it . For the accel enrichment, descriptors are rpm and D3, but TPS is CB, maybe is...

Last Two days I made some tests with the ostrich. WOT is now good, PT are better (not perfect but I have To work on it again), but I have some problems with idle which is verry erratum (sometimes rich, sometimes lean), but I think that's because injectors are biggers (270cc). I had To lean a lot at ...

Evil

Are you sure about position of TPS and CPS? A bad positionning of one of them can cause many problems. To trace the tables and adjust fueling and advance, you need to use tunerpro RT (Real Time), so you can see where you are in maps and adjust values, e.g if you are at a given load/rpm, thÃ© point o...

Evil

If you have an ostrich you can trace the tables and adjust fueling and spark with Tunerpro. Are you using m50 sensors? Specially the cam position sensor? What idle valve are you using? Do you use the maf from the m50? If not, you're running in alpha n mode and thÃ© tables are surely not adapted for ...

Evil

Hi Aboutton ðŸ˜‰ 1. Yes I have switched wires 1 and 3 on the TPS plug . 2. Ok I see what you mean. 3. I know that no airbox will affect a low end torque, but thats an option that I dont neglect, maybe I will come To it with a bigger MAF when the actual setup will work fine. 4.you're right, it seems ...

Evil

You're absolutely right, thats what I meaned by wiring the TPS signal on thÃ© MAF plug: TPS signal will be use for both TPS and MAF in parrallel. For the airbox + MAF, maybe I could do it in the future, but I have to build the airbox, it will ask a bit of work so I want first To make this setup work...

Evil

Little update: My TPS had a little clearance with the throttles shaft, solved with a better adaptatif with no clearance. Now voltage changes as soon as throttles move, and response on acceleration is better. I'll receive my Ostrich 2.0 soon, more update when it will be there. I'm thinking about wiri...

Evil

Huge thanks To Aboutton for the enrichment table, now I will be able To do some work on this ITB setup.
The enrichment table is already at top value at low opening, but I have To solve the TPS problem and Perfect my fueling before doing anything else!

Evil

Thanks Aboutton, I'll try it as soon as im back from work ðŸ˜‰

So I've take a look at the 506 xdf/bin. I've try to found the same table in my 403 bin but found nothing with the 3d viewer...

Evil

Ok its a good idea, i had found the tps definition by looking at a 413 xdf and bin To recognize the same table in the 403.Thanks for thÃ© idea! I replaced the TPS from gsxr by the m50 one, the range is better but I have again less range than with the oem throttle. I think I will definitely have To c...

Evil

Hi Hairyscreech, and thank you for your answer!
I see what you mean, I'll try To adapt the M50 TPS. Do you think that tuning the TPS dÃ©finition table, To tell the ecu the higher airflow in low throttle opening, will solve the acceleration enrichment problem?

Evil

Hi all, My car ls a bmw e36 with a m50b25, 403 dme. This week I put a set of individual throttle bodies from a 1000 gsxr. I run with no maf (unplugged). I have some problems of lean AFR in fast throttle : AFR reaches at 16/17, and then go down to 11 (I run E85, my wide band controller is a Zeitronix...
