Auto chipping info

[Bird333]

Well apparently the thread that discussed this has disappeared. But anyway for those that might be interested. Thanks to 'starchland' providing info; the ecu that 'wills_accord' used in his setup has the '1720' circuit board which was different from what I used that didn't work (I had the '11F0' P06). So there is a slight possibility that this circuit board would work out of the box.

i have also heard talk of the 11f0 auto ecus not working when chipped...

so which ecu dosent work, chipped, the 1720 or the 11F0. Iam completing a g23 (f23/h23) hybrid swap in a few weeks and iam currently setting up a 1720 P06 auto ecu and a jdm h22 tcu for my car. I need to know

i just realized that only the mods can see that...i even posted in that thread today lol. The thread starter is on a mass ignore list for bad behavior so thats why you can't see it...cause he started the thread.

I replied this tho today:
Bird333 i just read that you had the 11F0 circuit board when you tried out the p06. Some of, not all of, the 11F0 boards that are automatic need to have IC13 desoldered and taken out. Or else there will be a solid CEL. I don't remember exactly why but i remember it was a different type of high switching transistor than the others from IC14 and IC15. I've only ever encountered the problem once but you may have had the luck to run into the same problem. Just some info to help you troubleshoot. I didn't realize it until you mentioned it. So if you did have a p06 with a 11F0 board and IC13 had a 5 pin high switching transistor this could definately have played a part on how the ecu ran your auto because it controlled something in the ecu regarding the auto transmission. I don't remember how it effected it because it was almost a year ago but i do remember a solid CEL i couldn't get rid of until i desoldered it.

Well, the jury is still out on this. My 11F0 didn't work properly. I guess the only way is to test things out. I don't know about you, but I would like to have a working solution that didn't rely on using one particular version of software.

Ive heard that the auto's can only use the 1.66 version of uberdata, which sucks because 1.7 has datalogging, but i guess something is better than nothing. Mine may be a real task iam converting from obd2b to obd1 with the boomsleg auto conversion harness using the p06 and a jdm accord SiR tcu.

ubers datalogging was never that great. ECUcontrol is better and also what i use for my customers. Even has digital autometer phantom gauges.

Question for those that successfully used a P06 in an auto. Did any of you have a flashing 'S' (sports mode) light (for '90-'91 Accords)? Apparently in those cars the 'S' light would flash if there was a tranny problem instead of 'D4'.

[Accord R33]

neither of the two autos iv done had any flashing lights, or CELs

Did you tell Boomslang all the parts you were using so they could customize your harness? I am paranoid, I would trace out each wire anyway.

[Egi7]

I told Boomsleg that I was using a auto p06 ecu and a jdm H22 tcu on a obd2b vehicle. They told me its not a problem, took about a week or so to send me the harness, looks pretty nice. I havent tried it out yet, iam waiting on a basemap from MRX and my H23 exhust headers. Iam too scared to attempt to wire an auto obd conversion myself....lol
