No, I meant the other car you mentioned that shows it working properly. Is that car automatic or manual?

This is the review video I'm talking about. Was the car in that video automatic or manual?

Based on your video, it looks like there are multiple issues. 1) Not shifting up without lifting off the gas 2) Not blipping on downshifts 3) No ignition cut on upshifts 4) Lazy full throttle shifts I'm going to assume that the firmware/tune on the ECU is meant for a manual car and is missing functionality to make it work right. For 1 and 4, I think the TCU isn't seeing a valid load (or similar) value from the ECU. RPM, TPS, vehicle speed are all shown, but what about engine load? The TCU will use RPM, TPS, vehicle speed AND engine load to determine when to shift. I would assume it also uses load to determine how hard/fast to shift. I would try logging anything related to engine load on both ECU's, and the TCU to see what is different between the stock ECU and the motec. For 2 and 3, those will be trickier to fully solve. For shifts done manually you'll just need the tune to cut ignition on upshifts and blip throttle on downshifts. To make it work on automatic shifts, it'll need more integration with the TCU so the ECU know that the TCU is shifting (since it won't have input from the shift up/down switches on the steering wheel). Why do you have the motec in the first place? It doesn't sound like your setup needs anything beyond what a stock ECU with EcuTek can easily handle, and that won't have all these integration issues.

The motec has this feature . But somehow it did not working And if you really watched the video.. i explained everything that the data from the TCU is the same that the motec reading. Even before i start the engine And of course this is the first thing i ve been doing to the motec. I calibrated everything down to the last two digits behind point.. So trust me the tcu and ecu are sync perfectly. Yeah i agree about blip and flat shift. I defenetely can configure it later when done with the light throttle thing The point is. This is claimed to be plig in solution with all the stock ecu has. And it came with a packages and map that already tuned by motec guy. They claimed all the same feel with stock ecu. I have edelbrock SC. Just not yet installed. Before this problem fix. Motec are still working on this. They also feel there is some lost or interference in CAN comunication system between motec and TCU. I already scan the can with CAN analyser and send them like 250mb of 15 minutes driving on 500k Let see where it goes. |

Did motec even cert the m150 for autos?
Quote:
Let me clarify this... It's possible that the motec is sending the correct can signals, but without the correct headers for the TCU to even recognize that they're meant for it. Some systems send a single packet type with the same header that multiple can modules look for and receive and some send multiple types of packets with different headers for the different modules. I don't know which the 86 platform uses. If motec claims the M150 works on automatics, then I would say, this is something that they're going to have to address, because as far as I know, NO ONE has found the can values for the TCU control.

Based on your setup, I would be selling this and going back to a stock ECU. I don't see any reason why you would benefit from the motec over EcuTek on the stock ECU, and it's WAY more headache. You won't be able to make more power over the stock ECU, so why bother?

Yes i was thinking the same I am contacting ecutek as we speaking But with ecutek license for open all cars.. it is pretty damn expensive too Lets see where i will going from here. And yes you right. I tried to tweak and tune the stock ecuflash map to the motec table, and it works better Today i just manage to translate the rom language to motec for the DI / PI contribution Car feels fantastic. I did not tune it yet. I leave the close loop do the job. Motec close loop has never fails me. It really challenge me to not giving up on this motec.. although the motec guy has given up on me. And put the blame on my car. Silly. Right ? |

Baud rate?
Quote:
^ I assume it was verified that the CAN baud rate is 500k? Looking to implement a Haltech adapter of sorts with a micro-controller and trying to figure out if I will need 2 CANBUS networks. Haltech's canbus speed is 1M (sport 2000) Thanks if anyone knows |
