Now I cannot select or remove datapoints.

Also access violation when sometimes trying to view these data logs.

Anyhow with my million emails to haltech, hours of dyno time and three other haltech experienced people looking at my boost transition issues Ive just about had it.

Hello Ian,

For this I simply don't have an answer.
Have you tried adjusting where the staging point actually occurs ? At what primary injector duty cycle do the secondary injectors engage ? All I can think is that the secondary's are not being switched at a suitable time.
I have clearly read that this did no occur on your E6K but it will be worth looking at.

Scott,

Injector #1 and #2 is 13.4ohms,
Injector #3 and #4 is 5.2 ohms.

Fuel pressure is 40psi base and appears normal ie increase during boost pressure and decreases during vacuum.

As mentioned before the old setup "E6K" did not do this.

Thanks for your help. I don't want to change to another computer but this is annoying to drive on the track when I am on the 0psi steady..............

Have a good weekend,
Thanks,
Ian

Ian,

Your maps look ok, but I can obviously see the dip in AFR on the staging point. However in tuning many staged setups I have never seen this issue or had any support problems with it.

Please check the impedance of your injectors with a multimeter (both primary and secondary - all of them) as well as checking your fuel pressure, this may give a clue as to why the secondary's are being controlled so poorly.

Scott,

I have attached two datalogs for your review. As you can see if I decrease the fuel in the staging bar map the transition will be lean from low load to high load but still rich from high load to low load. If I increase the the fuel in the staging bar map it is rich from low load to high load and rich from high load to low load. I can get transition tuned fine from low load to high load but if I hold it at 0psi the computer gets confused and it just stays rich and is always rich no matter what traveling from high load to low load.

I had a friend who has tuned his car and various other cars play with it (2hours on the highway) and he agrees that the computer system is not acting as per design. I have also spent hours on the dyno and days on the street just for this transition issue.

I also went from common mode to primary mode and the same condition exists. What appears funny is the boost transition map still has an effect in both modes. If I set the boost transition map to 0 the car will not even cross the boost transition. Also the first bar in boost is approx 2.8ms but the staging bar map needs to see over 3ms to have a decent transition?

I hope this makes sense. Its driving me crazy and I did not have this issue with my old e6k and looking at other tuners E8 maps it doesn't look like mine is any different.

As per haltech usa I have the fuel injectors set at 3amp/.8amp on stock 550cc injectors primarys and a set of fords 1600cc secondary injectors. I was told that the haltech can control both high and low impendance injectors at the same time.

I hope I can get this figured out.

take care and thanks for your time.

Ian

Hello Ian,

There is no data log that I can see and offer any more advice. Are you injector current control settings correct ?
Is there a reason why you do not want to try going to Primary Hold mode ?
You should be able to run the engine transition smoothly using common mode, what size are the primaries and secondary's also ?

Scott,

Thanks, I played with it again as I have spent already countless hours on it. I can remove fuel but the during low load to high load it goes lean. But still the issue of high load to low load goes rich as you have seen on my datalog provided previously. Its almost as if the program can negotiate the transition properly.

Primary hold mod instead of common mode may be required but I don't want to change it.

Is there some sort of datalog i can provide you with?

Thanks,
Ian

Hello Ian,

It looks like this is occurring at the "Stage Injection - Extra load bar map" (under maps > fuel correction maps)
The extra load bar is located between your primary fuel map, and secondary injectors enabling (Where the colours in the 2D map changes colours)
If you take some fuel out of this map the transition will be much smoother, which is essentially what this map is there for!
If there is anything else we can do please let me know,

Scott,

Hope you can help.

I have the Haltech E8 1.89V running on a 1988 Turbo rx7 running a T04b turbo. Attached is a copy of my map and a datalog. (let me know if I can datalog anything specific for you.)


Problem Statement:
Crossing the boost transition is not a problem. It appears light throttle through is fine. In the process of light throttling down from the boost to atmosphere pressure the haltech appears to dump fuel into the engine. (I`m fully aware that once you rapidly release the throttle you get a rich spot but this like when I am at the track slowing decreasing throttle and crossing from the boost into atmosphere map it dumps fuel) Also sometimes when trying to just drive at the boost transition the Air fuel ratio gets pegged at 9`s. The Bar before and after transition if you maintain exactly that cell the air fuel ratios are correct.

On my old setup E6K I didn`t have this problem.

Can you help. Thanks.
Ian

 

The datalogging error was fixed be in the setup page removing the 8 or 9 previously selected datapoints reqested to log and just reselecting them.

No idea why but now after a datalog I can now select whatever datapoints I need to see.

Boost transition is still on going. So far I may just have to move this issue further into boost range.

Ian
