tjwasiak Posted February 26, 2015 Report Share Posted February 26, 2015 US is US, but I am from Europe. Volvo did those things differently 2.3 is > 2300, 2.4 > 2400 and 2.5 > 2500. Try to retard timing a bit. I would change VE map to make it run not richer then 11.5:1 as I just do not see any reason to drop useless fuel into engine.

Midnight Caller Posted February 26, 2015 Report Share Posted February 26, 2015 Well' to even things out, we're both talking about the B5254T, pre -99 engine I retarded timing more now, maybe it ran pig rich because of the knock fuel enrichment, and not because of the VE Map. Will write the ECU today and take it for a spin in the evening and see how it goes. I didn't want to retard timing that much at first, because I thought I made something wrong, but now seing the differences between the stock GLT timing and the T-5 timing, and added the 6PSI extra boost, I guess I should have retarded the timing more in the first place. I don't want to touch the cam advance for now. Thank you a lot ! Link to comment Share on other sites More sharing options...
tjwasiak Posted February 26, 2015 Report Share Posted February 26, 2015 If I were you I would try to use stock LPT timing with your increased boost. It might be just the proper setup. Regarding if your fueling is due to knock enrichment I thought you can check it in your log but I might be completely wrong as I do not own a M4.4 powered Volvo yet.

Midnight Caller Posted February 26, 2015 Report Share Posted February 26, 2015 Yes, I took the LPT ignition timing cells and put it in my bin in the 3000-4000rpm area where I have knock. Hope it will fix things. I'm only tuning at WOT, leaving the rest as-is, for lower fuel consumption at cruising speeds and low load. Link to comment Share on other sites More sharing options...
Turboforslund Posted February 26, 2015 Report Share Posted February 26, 2015 Hi, Have you guys tried to extract the differences in the 609 bin I did provide an xdf to? It's from a 193hp V70 AWD-98 (maybe a "LPT") // Turboforslund Link to comment Share on other sites More sharing options...
MrCain Posted February 27, 2015 Report Share Posted February 27, 2015 Damn..... Reading about the problems with the FTDI drivers im sceared to update my Windows... Did not run any update til october last year, think im gonna keep it so BTW: do anyone know wich update the FTDI is killing? Link to comment Share on other sites More sharing options...
venderbroeck Posted February 27, 2015 Report Share Posted February 27, 2015 They took it out. The newest driver wont brick it, but merely state the device is counterfeit and prevent the pc to work with it. Best not to update the driver at all. You can modify the last working driver to have a high version number. That way it won't be updated. Link to comment Share on other sites More sharing options...

Horses With Gas Posted February 27, 2015 Report Share Posted February 27, 2015 I know that in the States, the GLT is considered 2.4, but in Europe, they are badged as 2.5T. Yes, it's 2435cmc, but it's badged as 2.5T (I can take a photo if is sounds weird). That's why I said it's a "GLT" because I've been told before there's no such thing as a 2.5T As far as the fueling goes, I didn't touch the VE map, it's the T5 VE map, and the last line (8.02 load), when converted to AFR, is 10.69 at 5400RPM. I also gave up on WOT Enrichment (had it set to 1.1 after 3000rpm), because that took me to 10.4 AFR ! So that should be the value I guess ? I've now set Lambda to 4 for under 3000rpm, 3 for 3000-4200rpm, and 2 for over 4200rpm. I'll guess I'll have to pull timing a little more after 3000rpm to get close to the values of the GLT firmware. Regarding LPT 4.4: if knock is being detected at midrange rpm, try setting 'Lamba threshold for WOT' to as low as 3.0 at 2580 rpm. Link to comment Share on other sites More sharing options...

lookforjoe Posted February 27, 2015 Report Share Posted February 27, 2015 Applies to any Knock off FTDI chip i guess, would you like to try the modified drivers? they will allow you to install it, then you can use FTPROG to put the hardware ID back that gets set to 0000, after that it will start working like normal... so annoying. Edit, the only reason i recommend editing the FTDI hardware ID back is because this driver is considered "unsigned" and may not work with everything Thanks for the offer - Steve. Mine wasn't bricked, since it works on the old laptop -this is the driver that works fine for me (for some reason [PrtScn] didn't work for system info windows - it works for any other screenshot?). Turned out my problem with the replacement laptop was the COM port setting within TunerPro - it was holding the port info from somewhere else. Aaron helped me figure that one out yesterday Link to comment Share on other sites More sharing options...
venderbroeck Posted February 27, 2015 Report Share Posted February 27, 2015 That won't do nice things to your mileage. I would pull some timing first instead of making it run very rich I think. Too much timing isn't going to produce more power even if you can tune out the knock with fuel. Link to comment Share on other sites More sharing options...
tjwasiak Posted February 27, 2015 Report Share Posted February 27, 2015 Just finished reading this topic from 1st post... (...) 1. The IAT read by our ECUs (S70, not 850) are not read in the intake manifold (where the real IATs should be read) but in the MAF I think (which normally will correspond to ambient temp) so the IAT read by our ECUs has no purpose when we are talking about heated air coming from the turbo! Thus, our ECU's are not able to lower timing or load or whatever based on real/manifold IAT. 2. I've read all the parameters that our ECUs give us plus boost and AFR. No, Im not logging neither IAT at the manifold nor EGT (for that I would need a proper IAT sensor and gauge + a proper EGT probe and gauge which I currently don't have). 3. Your approach basically is to reduce load and/or timing to avoid knock whenever knock appears and whenever temps are high. Well, we all know that reducing load and timing will lead to less knock of course BUT our goal is not to reduce load. The goal is to maintain load as much as possible provided this load really means more power and adjust timing accordingly so we won't knock. Of course that in an extreme situation (when you are just blowing f**** hot air) it is better to reduce load because the air is so hot that we are not producing any additional power with that high/higher load. But Im not discussing extreme situations. However, in a situation where you are not blowing stupidly hot air, it is better to maintain load and reduce timing due to increased charge temps (like the ones you have in higher gears for extended pulls). 4. If I would apply your theory of reducing load and timing everytime charge temps increase I would just stick with a NA car, right??? A 4th gear pull in the road from 1500 to 6400rpm takes about 27secs. I must admit I can not commect about real differences made by ECU as I do not have a car to do test but someone here was wondering why there is such a big difference for just 10* difference of IAT. IMHO it is just because Bosch/Volvo transfered 10* of difference in input temperature to much higher difference in real fresh air temperaure in manifold/by the intake valve. That said you can use ambient temperature for timing/fuel adjustment provided you are using some factor to make it correlate properly. As you said road pull takes 27 seconds, shorter dyno pull was just 29 seconds. Do you think it is so huge difference? You stated airflow at the dyno was lower (albeit boost was 10% higher) but you still had knock and your conclusion was that it was lower load that caused your knock... Taking all you have written into consideration I would not try WOT pull in 3rd nor in 5th gear running your tune as it will just kill the engine. All I had been writing was about having proper tune. Tuning only WOT area at one exact gear at exact ambient temperature is far away from making even only good tune. But it is just my opinion...

Horses With Gas Posted February 27, 2015 Report Share Posted February 27, 2015 Hi, Have you guys tried to extract the differences in the 609 bin I did provide an xdf to? It's from a 193hp V70 AWD-98 (maybe a "LPT") // Turboforslund It looks like there are significant differences between the 607 rev5b and the LPT file(s) you posted. Just a sample of those changes: the axis differences, boost and ignition maps, "lambda threshold for WOT" in the LPT version exits STFT at much lower load and RPM value than 607. Also interesting: the different formula used for the knock-detection map. I'd like to try a non-immobilizer version of your LPT files. Link to comment Share on other sites More sharing options...
PsychoBeano Posted February 28, 2015 Report Share Posted February 28, 2015 Made some changes to the wiki; re uploaded all the bins/xdf/adx files I have and a few Ive seen posted since the droid site is down. still looking for citations but ill try to add them to the wiki when possible. Also reskinned the latest adx I had (REV5TMM9AFRa.adx) to a darker color scheme. I got this from one of Hussein's posts and I recall it being setting for an AEM Wideband setup so it may need some modification if you are using a different wideband controller. Screenshot: Available here. If anyone else can upload and/or post any other bins/xdf/adx files that they may be using to the Wiki would be awesome, I believe I saw a rev7 being discussed at some point but it was never posted publicly Link to comment Share on other sites More sharing options...
