Re: Ebl flash tune
Ok everyone was playing around on it tonight i have been increasing the kpa 100 column by 2.00 percent in the sa main table and extended table and have noticed some change in smoothing out but as soon as i get up to 3300-3500 rpm it starts to pull back timing again so where do go from should i keep increasing the column by 2 and see how it goes from there i may have found someone out in bristol rhode island that i might be able to get the car out to him and he can self tune it for me but until then im gonna keep tinkering with it and see if i get any closer to fully smoothing it out all the way to 6000 rpm

Re: Ebl flash tune
What would cause a mechanical knock the bottom end has like 6000 miles on since rebuild oil pressure doesnt drop below 30 psi fully warmed up and idling only knock that incould think of is from the rockers maybe being to tight from doing the valve lash

Re: Ebl flash tune
Anything that goes bang-bang. Loose exhaust. U joint/driveline/gearbox. AC compressor. My snowmobile set off a KC's until it was broken in. Fix was adding a thin plastic washer under sensor. Some sensors are very sensitive.
Adding high octane fuel 100+ temporary is a way to rule out mechanical.

there is no loose exhaust I do have a small exhaust leak out of the header but that really shouldn't throw the knock sensor off nothing in steering is loose and the ac compressor isn't hooked up for the compressor to kick on and off.
I actually found a guy out in Bristol ri that the car is gonna go to, to get tuned fully he knows the ebl set up very well he will also be able to put it on the dyno and fully get it dialed in he is also willing to weld in my sfc all of this for 600 bucks so I cant pass this down

Re: Ebl flash tune
167 posts, and he was given the information needed to get his EBL hooked up, engine started, and running. There is only so much after that in which tuners can suggest online without visually seeing that elusive datalog we kept asking for pages ago...

Re: Ebl flash tune
who should be ashamed this is my first time trying to figure this out beginners need to start off somewhere to figure somethin new out but yes it is aggravating that its not fully running right yet these guys sure helped out a lot though its awesome that they put time into replying I can upload a datalog to see if you can figure out where I'm going wrong at maybe u can see something that everyone and myself is missing

Re: Ebl flash tune
Ok so i know i havent posted in a while i was wondering if the knock sensor would be the main cause of timing backing out ???? I pulled the knock sensor and found out the part number is a original so its about 25+ years old. I decided to take it out and found out that it had tons and tons of rust built up on top of it and also the spring inside was all corroded would this give a reason for timing to back off when above 3500 rpm

Re: Ebl flash tune
A bad knock sensor being replaced with a good one can only help things.
It would be great to sit the car in the driveway, datalog for a couple of minutes and then share that.
It's not too hard- use the WUD, create a session, close it out, and then attach it.
There's nothing to be ashamed of- no one expects your BIN to be perfect or that your car and set up is somehow bad.
Everyone here wants to help. You know you want some help otherwise you wouldn't be here.
It's just that everyone here is blind with respect to what you have going on.
If you share a datalog- any datalog at this point- we can look for things.

Re: Ebl flash tune
Bringing a dead post back to life so everyone is back at it after redoing the exhaust, oil pan etc. motor is back in the car didn't change a damn thing expect headman headers and custom y pipe with cat. I recently got the exhaust done and everything went great with it car ram was idling etc. now all the sudden car doesn't want to idle for anything replaced the iac thinking that was it nope still noting did the whole reset key on disconnect iac plug key off plug back in, turn key on should reset go to start same thing no idle. I'm getting really f ing fed up with this f ing ebl you all said it would be simple but clearly not and trying to get rbob to help is like hitting a million f ing dollars will never happen. Another thing too is that no freaking shops around my area want to deal with it cause they never heard of this shitty tuning program so now what I'm just out 500.00 for all the money I invested into this could of had a LS built and in the car somewhat ready to go off to be tuned
can anybody help out with this that knows what the hell could be wrong

Re: Ebl flash tune
First off you need to claim down. Alright after reading most of this thread. The Dynamic EFI EBL is a great product if you have great math, reading and mechanical skill. You have had this product for over 2 years now and I have notice a few things. First I've notice you do not give all the info or don't explain everything to the fullest. Second based on you questions that you have asked and the replies you get along with the you responses back. you either don't under stand and or you are choosing not to follow those steps everyone has posted to help you figure what is going with your car. Either way you need to clam down and help us help you by data logging and post it or move and realize true tuning may not for you.

Re: Ebl flash tune
key on engine OFF are you seeing a blink of CEL then full on? If that is Ok that means the .bin is being used and is not corrupt.
In your data logs are you getting any error codes?
You could disconnect the IAC and run solely off the throttle stop screw to rule out the IAC issue. Make sure the IAC port is plugged so as not to have that leak. I ran mine that way for a year as IAC was not functioning due to cross wired. Possibly IAC is not opening and throttle blades are not open far enough to allow idle.
Datalogs posted would be helpful and will diagnose most ills.

Re: Ebl flash tune
ok guys I know I haven't been on in a while been busy with other things so was playing on the car and noticed it's definitely a iac problem. As soon as you plug it in you see the steps slowly decrease on the wud. But if you unplug it and start the car it will idle at 950-1000 rpms im gonna try to upload a data log of it tomorrow so you can all see what the hell is going on

Re: Ebl flash tune
I am not sure but I recall that the WU display shows commanded steps not actual physical position of the pindle. I would look at the IAC when engine cold key on engine off to see if it cycles open...closed... and then to open at cold coolant position before you crank. That would indicate it is functioning.

Re: Ebl flash tune
Ok so was playing around on it again last night car runs somewhat smooth with the iac disconnected as soon as you plug it dies out I removed the iac and tested to see if it would open and it doesn't move at all I'm getting power out of 2 pins and that's it. Now when I did the pin change I looked it over and the iac has nothing to do with the pin change to switch it over from factory harness to ebl speed density harness. So the harness pin change isn't the problem I'm really stumped on this what the hell could it be for not letting the iac energize.

Re: Ebl flash tune
Ok so I decided I'm giving up on this ebl program going a different route not able to figure this crap out. Thought it was gonna be easy but clearly not I'll be posting it up on the classified ecm and harness. I wanna thank you guys for throwing your knowledge. I would like to sell it on here to someone that knows tuning and could need it for their build.
