Is your SES flashing? You might have to reload the Bin into the emulator. I have already had it where I made changes and forgot to save before shutting the engine off. When I restart, the SES...
My dads 71 vette (350) was knocking last year. It never made any noise when it was cold. After warm up and no load, you could really hear it when you goosed the throttle. The oil pressure gauge...
Does it have a working oil pressure gauge? If so, what is the oil pressure? Is the noise present when the engine is cold?
There are two wires going to each injector. The white and red wires should have 12V all the time when the ignition is on. Can you confirm this? The ECM creates the pulse by providing a ground...
Are you using a TBI distributor (Or a TBI ignition module)?
For sale is 1227747 ECM with 27SF512 chip conversion. The ZIF socket is the higher/stronger socket. Unfortunately, if does require the cover to stay removed or a thicker seal is needed to gain...
I'm not sure if this is the best way, but I record what MAP reading and RPM knocks occure. After getting a rough idea which area's are problematic, I'll remove timing from the cells and smooth the...
Record a log of it accelerating from a dead stop and post it.... Also, post an updated bin.....Did you modify your timing table? The bin that you posted has an crappy timing table. Try the timing...
Thanks Fast355! I understand how it works now. See the attached picture. You can change the bin thru the hex editor or the thru the parameters defined in the XDF. Stoich AFR is already defined...
Just when you think you have things figured out this happens......Here is an example: VE tables are tuned with the same gas (no ethanol) and all BLMs are perfect (128) while in closed loop.... The...
Yes, you will need to download the XDF, ADX and a starter bin. This tread would be helpful...
Hi, I thought I would share a TBI project that I finished a couple years ago. The only difference in the video between then and now, is I changed the distributor and tune slightly. ...
Yes, it’s not a bad idea. Your values in your open loop tables (including PE) will be closer to reality. Which means they might need to be tweaked slightly if you change it. If you have been...
There are significantly more options with these later versions. They rock!
If you have any questions, I converted the 351W in my boat to TBI. With spark control.
Use this mask:
I'm not sure why GM set the 7747 up this way. It would make more sense to have one VE table that goes up to 6400RPM.....I'm not sure if I understand your question, but you can 0 out the adder table....
Set your TCC parameters like I show in the attached picture. The parameter that is circled is the one you want to play with. Currrently, it will energize the solenoid (and downshift) when the...
Set idle off to 25 and idle on to 50.
The ECM will only be controlling the kickdown relay. The other parameters relating to torque converter locking and unlocking will be disabled. In other words, it doesn't matter if its a 3 or 4...
sounds like you need to get that vacuum leak found. Somebody suggested getting a heated o2 sensor, did you try that too? Post the data log, I'm curious if the O2 swings are still on the lean side. ...
That's all right. I had my share of questions when I started... Yes, the 27SF512 chips are reflashable. For a starting point, I would buy (2). One for the ecm and one for changes.
I leave my lid off (since I'm swapping chips a lot). However, you can space the lid up with weather stripping to make clearance, if you are concerned with dust getting in. Also, that picture shows...
That picture is not of the G2 adapter, its a 2timer. This is not what you need.
