The ECU will require an OEM type narrow band O2 sensor to adjust fuel. Do yourself a favor and make sure to get the heated narrow band sensor. The wide band sensor is an additional separate sensor...

You only need a single 2 pulse per revolution VSS sensor connected to up to the Pin F13 on the ECU. Yes, the ESC is built into the 7427 ECI.

Dave, Thank you for helping out with this. When I use the $0D ADX file you provided above, the timing values in TunerPro and your spreadsheet match the values you show. As a test, I re-loaded the ADX...

Dave, Thank you for providing the timing table and the screenshot of your altitude timing values. Some things I take away from the information you provided.

1: TunerPro does not record the actual...

Dave, Thank you for sharing the datalog. I see many similarities between the datalog you provided and mine. Do you by any chance have the timing table that was in use when the datalog was recorded?...

UPDATE: I just remembered I collected a 30 minute datalog while in the San Juan Mountains. After reviewing, now I'm VERY confused.

1. I completely forgot being at 10,000 ft only represents...

I have a very mild SBC 383 in a Jeep using a 7427 ECU. It has been used primarily off-road all over Texas, Oklahoma and Arkansas without issue. We just returned from a trip to the San Juan Mountains...

I suspect your furl pump may be getting weak and loosing pressure under load. This causes the engine to go lean when under load, which will cause knocking. Letting off the throttle reduces the load...

You can find the TBI ECU pins on Ebay. I bought a pack of 15 for around $10.

Someone also previously mentioned that you need to use the sensor ground when measuring the voltage on signal or...

The download worked today.... Not sure what happened yesterday.

I'll check it out...

1967, Post your timing table so we can have look.

For some reason the link the website flip flops back and forth between Russian and English for me. Where can you buy one of these and what is theretail price?

Tayto, Thank you for the link. I went to the website and tried to download the file, but for some reason I couldn't get it to download. The description of the software makes it sound very much like...

I decided to enable Closed Loop with locked BLM's and INT's at 128. Sure enough, after enabling Closed Loop but with locked values, the Wideband AFR values changed in Dave's spreadsheet. After a...

Equipment:

ECU 7427 on $OD
Mostly stock SBC 350 in a Jeep
Small computer compatible camshaft
GM TBI BJLH based BIN
Have a wideband O2 sensor inputed in the Linear ERG input
Larger 46MM...

This is great firsthand information. I'll will search for that same adapter or another adapter that is divided all the way to the gaskets in the manner you described. I was overthinking this, but...

This is for a 350 TBI Jeep trail rig that will be running a Summit K1102 204/214 RV cam in a 1970's block and heads. Would a 46m TBI work better with a standard spread bore Edelbrok Performer intake...

I have no need for EGR and was originally looking at either the spread bore performer or spread bore performer RPM intake if I stay with the TBI. Unless I am mistaken, it appears the the TBI throttle...

I finally opened up the box for the TPI that I purchased over ten years ago. I dug through the box and it appears that all intake components, distributor, painless wiring harness and ecu are there....

Buddrow- I read through this site and made some progress last night. I discovered that I have the 7747 ECM. I also figured out how remove the factory style 2732A chip from the 7747 ECU and I...

After a long and unsuccessful journey with a TBI 383 and a "popular" TBI mail order tuner, I have been very reluctant to make any changes to my SBC 350 jeep with a TBI, factory cam, factory TBI...
