From what I have seen in the ZF we can change these values and increase the temperature that it allows flashing. I would not risk this as there are comments like if the chip is over a limit then flashing will fail. I am not sure what state that would leave the ZF in and if it could be recovered.

Rab, Are you doing this because the injectors on LPG and Petrol are not matched? Something along the lines of having factory petrol injectors and LPG have been set up for higher power? I also have a JTG system on my Territory and have looked at the IMRC but I have not been able to work out if I can use the signal from the JTG system to tell the PCM the IMRC is in a different state but mine is a BF. If the IMRC can be only be used the other way then I might get it to turn on the petrol injectors to supplement the JTG and maybe water/meth as well. Once Rolls and I get the Workshop version/scanner done for PCMTec I might be able to have a play.

Puffwagon, thank you for the feedback, greatly appreciated. We took the advice from the lawyers to it will probably be legal speak. For information of the DIY Tuner forum: Enthusiast is at a tuning level just beyond what HP Turners offers, does not include ZF tuning and costs $300 + GST Professional is at a tuning level beyond what SCT offers for both the PCM and the ZF (Editing working, flashing under development), $600 + GST Workshop is effectively OEM level tuning with extensions they do not have. Not for sale just yet. PCMTec reads the calibrations from the car,like HP Tuners and Sniper. Does not have their limitations in determining the calibration. Demo version is Workshop level

Boost a pump does not change the life of the pump, this is well researched and is a common misconception. I have been running it for over 5 years now and done 250,000kms on it. Pre Ford using the same injectors so mine is JTG on a TTG. Wifes car, tuned down to 390awkw, one pump plus a lot of secret LPG tweeks learnt getting there.

EcoLPi yes, I was told that Ford had to dumb it down as it had about 220kw so it would look the same as the petrol jobbie. Anyway we can tune them and yes if you find the matching PCM you (and we do mean you Ralph) have access to do what every you want. All the cars I have done on LI LPG make quite a bit more power than 98 but it is work getting the fuel once you get above 360rwkw on a turbo 6. Also there is another way to do fuel pump regulation, the old boost a pump (fuel pump voltage controller). That takes a single pump from about 300rwkw to over 400rwkw. MSD is programmed on pressure, which is perfect.

Ford does use a returnless system in one fuel type in the Australian Falcons. It can be done. Only available in PCMTec

Rolls (highly likely) and I will be attending the Heathcote drag meeting this weekend. It's the Sydney vs Melbourne Street outlaw meeting. PM me if you are going and want to catch up.

Much easier to read the asm and work it out. You get traction after reading a few million lines We are identifying all the routines we can and using them as a hint for where the parameter is used.

The existing tunes are extracted like HPT and Sniper do. The software has the capability of determining the calibration even if the calibration has been "corrupted" but this may be limited to the Workshop version.

If you mean existing software like SCT, Sniper or HPT then I am not sure. I don't think thing SCT or Sniper community think it is lacking but the BA/BF community on HPT are not ecstatic. If you mean our software then not at all, people have reported back that the "other products" do not have them either. In fact we have things like the exhaust cam retard that no one else has. What is being demonstrated here is that there are a lot of parameters we have found and the software is helping getting them defined for the customers. Our aim is to make the product flexible enough to handle the "missing parameters" and automate the population of them across all the calibrations. Not sure what other products have these features though Does anyone know if SCT has the boost sensor mapped yet or if HPT have put it into the BA?

Joe, yes that is the way the software is built. We basically find all parameters in the calibrations (secret squirrel stuff) and, as the software moves to Beta, allow the user to define what the parameter is and, if they want, submit it for everyone's benefit. At this stage I am doing the extra parameters for our Alpha users. You would have seen the post about the exhaust cam control but there are extra exhaust cam based speed density tables, speed based cam tables and numerous other spark tables. It is very exciting what is actually available for tuning.

A bit of an update for the Rolls software. As some of you know I am the one helping Rolls in the background hunting through the assembler and finding new parameters and have just completed initial testing on a new feature for this software. I have been able to track down the independent control of the exhaust cam for the XR6 turbo and yes we have control There is a bunch of tables missing from the other products that I have found and have them in for the first release (TBA). An interesting one based on vehicle speed but currently a constant. So now the fun will begin. IH8TOADS pointed out we could do ghost cams and we have someone testing this as well. So higher overlap cams may be controllable at idle as well as removing the stuff Ford put in to reduce back pressure in the higher rev range due to the factory exhaust. I believe this is a first for us. We have been told it is not in other products.

Maybe but if that table is mapped incorrectly then you are looking at the wrong data and publicising it based on incorrect information. Was the stock injector offset from the same calibration? HPT does not have the Global Spark Adder plus a whole heap of other stuff so who knows what the final result will be. 1 degree may be on the money with the addition of these other parameters.

Maybe but you should at least know that you fully understand what the tuner did. If the tuner used something like Sniper or SCT (or built on a tune by ones of these products) then you will not have the all information in HPT.

Just be a bit careful here as it is possible that HP Tuners may have mapped Injector offset incorrectly. It would not be the first time they had injector data wrong. If you want you can send me the tune and I can check it is mapped correctly. Kinda agree with IH8TOADS. It is all very well to say a good tuning shop did this but to actually narrow it down is harsh especially when something like HPT is missing quite a lot of the tables and scalars these tuners use.

Alex, Given you have a done a debung then you can expect around 230awkw with a decent tuner up from about 180. Bigger injectors will net you about 250 but you will then the intercooler will be an issue. Pit Lane is a long way and ratter will struggle as he does not have a 4WD dyno (and has to outsource it which makes it expensive) and you will have to buy an XCal. There is heaps of information on this and results on the other forum: http://www.fordforums.com.au/showthread.php?t=102230 And if you are interested Dave got this result with water injection:

In HPT you can cycle through the units to get the display you like. And as Rolls pointed out you get what most quote as an offset = (breakpoint* (1/lowslope_lb_s - 1/highslope_lb_s) + offset_sec)). And if you have Ford data you can calculate all the GM/Chrysler data from these equations for varying voltages and pressures.

Sniper has more parameters but cannot do the ZF and TMAP/Boost sensors and I don't think it can do DMR scanning like HPT and SCT. It also allows you to store the tunes in the flash tuner so that you could have an e85 tune and a 98 tune. Sniper interface is, supposedly, less user friendly. HPT does all of this except storing tunes on the flash device and is reasonable for the FG . It also has a great tune compare function. It is not as good for the BA/BF but Eric (HPT) says he is going to get back to these soon. Both Sniper and HPT read the calibration from the PCM. SCT does not support home tuners. I would recommend HPT as at least you can log what is happening and compare what has changed between your tunes and others, even across different platforms. Have a look through Jet tuning pages to get some ideas on its capabilities.

For all the tuners using HP Tuners: Eric Brooks has done a massive update to the FG Coyote tables and scalars. Things like T-MAP & Boost sensor calibration, gear based boost control, lost fuel and the list just goes on and on. There are things in this release that are not in SCT or Sniper so it is a big release for us self tuners. Here is a link to my post outlining the additions. http://www.hptuners.com/forum/showthread.php?54927-Eric-s-FG-BIG-update His plan is to finalise this calibration and then roll it out to the rest of the FG and BF Falcons (well what translates anyway). Way to go Eric and HPT

Agree with turbotrana. I have had success with the delay. Increased it to 5 minutes to get my readings once. Think the max value HPT is 65000 seconds which is over 18 hours

Two different injectors with different data (LPG and petrol) is the reason. In the end I just used a variable pressure regulator on petrol and upped the pressure to close to 5 bar. Got it close enough for LTFTs on both fuels to be +/- 1% VCM scanner can log commanded lambda. I use it. SCT has something like lamdbse but you can use the STFT value at WOT. SD tuning should be used when you make changes but only after you have your injectors dialled in. Much easier to fudge the slopes as long as you don't end up with Fuel trims over +/-5%. Fuel trims at cruise as close to zero as possible. Its very easy to get injectors scaled so that WOT is correct but less easy to get all the cruise trims spot on which is where your fuel economy will come from.

Rollex, the truth is in the posts above but you need to know what to look for. Here is my advice: Fuel base back to standard ID1000 data Fuel trims back ON Start Car, let it warm up and idle until LTFTs stabilise. Read LTFT data. Your injector will idle on low slope. Using this adjust you low slope until LTFT goes close to zero. Using same factor adjust high slope by same amount. So if your low slope is now 117 the High slope = 114 *117/125 Take for a drive and read lambda off the gauge. I am guessing your gauge and MPVI reading have not been aligned. Adjust you high slope until you get your lambda commanded as close as possible to the gauge reading.Using this method I was able to dial in a mates Bosch 0 280 158 040s in less than 10 mins over the phone. Many reasons why ID1000 data does not translate but my theory is that 1 litre of 98 weighs ~0.7KG and they use 0.75 as the weight of 1 litre of petrol when converting the data from n-Heptane to petrol. You should be able to get your lambda very close under full throttle. Leave the SD tables alone and just adjust slope to get close to commanded lambda as possible. Adjust your base fuel for fine adjustment, this will keep your LOAD value the same as factory and you wont have to recalculate these based on the SD changes.

Peppy, I have been testing this with bugsy on the HP Tuners forum but I have been able to get the 4 bar t-MAP and boost sensor working. Its not perfect because I cannot change the actual sensor data but we have a tune with boost control in the range 28-32psi, AFRs matching commanded and the car drives just like it does with the standard sensors (perfect). Timing is following the load values from 2.5 to 3.2+. Still early days but send me an email if you are interested. BTW 4 bar is the better sensor for this conversion.
