any difference in BA engine computers?
Have a 1995 BA 1.8 hatch and I wonder if there would be anything to gain (or lose) by replacing the engine managment computer with a unit out of a later model - out of a 97/98 1.8L car.
Would Mazda have improved the engines driveability over the ensuring years? |

Or maybe with one out of a KJ Laser? I wonder how much the software differs between the Ford and Mazda - exact same engines.

Nah, the Series 1/2 (Mazda) and Series 3 (Ford) have different plugs/looms, so no go there.
You might get a little benefit from a JDM ECU, but only because of the higher RON that it's tuned for.

But JDM engines have knock sensors and without the knock sensor connected to a JDM ECU it will go into crippled mode.
Plenty more you can do to a BP to gain power before you need to replace the ECU.

I'll double check but i'm pretty sure the connectors are the same for the mazda and the ford.
I'll need to look at the wire color code as well. Astina/Laser - same car different bodies! |

what he meant is that the models 1 and 2 were made when the company was owned solely by mazda, series 3 was made when company was bought partially by ford. series 3 is ond of 96 or start of 97 onwards and this differs by different door cards, the mazda wings badge (rather than the a-hole) and many different annyoingly small and numerous things.

Asanga tried my BA11P2 ECU in his BA11P3, and the plugs/looms were different - as well as not even running his car.

This is why I spent what I did getting the JDM ECU and wiring loom for the V6. Getting the distributor and AFM would have been fantastic except for the $$$ and the confusion.

Can you guys please give me the ECU numbers for all the series? 1,2,3 and also JDM. I got an ECU here of a BA but I'm not sure what series it is or from which year model.

BP Engine
Hi,
Reading this thread has me concerned about my plans. I have a late, 1997 BA Astina P3 Hatch 1800 BP motor which i am planning to install into a early 1994 BA Astina P1 Hatchback, with a stuffed engine. Is there any hassles to be had using the ECU currently in the P1 1994 Vehicle, to run this motor? The Donor Vehicle was a Manual vehicle, with the receiving Vehicle being an Auto. I was hopeing that the worst case would be haveing to change the Engine Sensors. Cheers Last edited by ahbasta; 25-07-2009 at 07:46 PM. Reason: More Info |

Hi guys - doing my best not to start another thread, but fearing I may have to...
Just purchased an ECU for my 1994 V6... Code on my ECU is KF 43A Code on the Jap ECU is KF 33A Now I was expecting a simple plug and play scenario, and it's not quiet so simple. The plugs are identical, however the Jap ECU refuses to run my engine. It lasts about half a second and stalls immediately. When I reinstall the stock one, it runs like perfect... Can someone tell me if I'm missing something here? What do i need to do to make it work, and is it worth the hassle. I was really after a plug and play solution... I am not certain of the year of the donor car, it is a V6 hatchback Lantis. Any help would be very much appreciated.

KF33 ECU advances the ignition way out and uses a knock sensor to reign it in when you use low RON standard fuel. Your engine has no knock sensor and if it did the AUDM loom doesn't have a plug or wiring to accommodate it.
You can run the engine but it won't rev over 4,000rpm and it's ping central. (experience) If you realy want to use this ECU then you'll need a JDM wiring loom to go with it. Good luck, it took me ages to find one and when I did it came with a Lantis shell. Sadly it wasn't a Type R shell
