Yes I have the same issue.

Greetings, I am removing all the factory wiring loom to make sure I don't have any issues with especially for the grounds. The factory ECU use 4 grounds. The link looks like use only one. Map attached. Please advise. Regards. Mazda GTX Base Map V1.pclr

Greetings, I am starting to troubleshooting something on my car and I noticed this jumper in my ECU. I looked at the manual and I don't find any information about what is that jumper for. It said MX5 1800 and it is disconnected. Please advise. Regards.

Greetings, I ask the same question on the Facebook and other link forums and they told me that it could be a ground issue to the ECU. I will post a log and map when I have a chance. Regards.

Greetings, I have a problem that I have been chasing for a while and I can not figure out what is going on. Mazda 323 GTX BPT Turbo 1.8 G4+ PNP. When the car is stone cold and runs until normal operating temp everything runs fine. After a while like 30-35 minutes running the car pushing different loads (boosting and cruising) more or less the car starts to misfire even at light load. I changed everything ignition related (coil, cap and rotor, module, new leads, spark plugs). Besides a new set of DW 450cc high impedance injectors the engine is completely stock. Compression is good 170psi all 4 cylinders so the engine is healthy. Now I noticed something. When I shut down the car for a while for 10 to 15 minutes and look at the ECU temp is around 100 degrees Fahrenheit . When I start the car again and drive it the misfire is gone. But when the ECU reaches about 115 degrees the misfires start under boost. When it reaches 120 to 125 degrees the misfires get worse even at light load. Again I shut down the car (engine still hot) to bring down the ECU temp to 100 degrees, start it over and the misfire is gone. So I am getting suspicious that the ECU drivers for the injectors and ignition are having problems (overheating maybe) and because of that the misfires. The ECU is in the stock location. Please advice. Regards.

Greetings Adam, Will do. Thanks for your support. Regards.

Greetings Adam, I just checked the trigger wheel on my car and for my surprise it has one big slot for cam and not 2 like the Miatas.(Picture attached of the trigger disc and trigger scope). So in this case is not a MX5 trigger. That MX5 trigger comes with the base map supplied by Link for the 323 GTX. Based on the post that you helped the other guy with the same GTX engine, I setup the same trigger parameters that you advised and now the dwell scatter issue is not present anymore and the car runs a lot better. Based on the trigger scope, those trigger paramaters are the correct ones for my setup? Also I have doubt about the trigger filtering parameter for both triggers. Right now is setup to Level 1. With the MX5 trigger it was set to Level 2. Because is the same optical sensor that the Miata trigger use, do I have to set that filtering to Level 2 also? Please advise. Regards.

Greetings Adam, About the stock ECU is that when I plug in the stock ECU back I don't have any misfires issues at all. Probably the stock ECU is sending less dwell that I setup. I will setup the 3D table for other things that tech support advise me. Thanks for your support. Regards.

Greetings Adams, Thanks for the feedback. Link tech support advise to me to switch to a 3D table and setup the dwell that I want the ECU to command to the module. With a 3D table, the ECU will command whatever I setup in the dwell table no matter what? I apologize but I want to fix this issue as again with the stock ECU for example I dont have this problem whatsoever. Please advise. Regards.

Greetings Adam, From my experience working with those cars, some cars comes with that CAS (four legs and one for home) with a hall effect sensor and some comes with the 4G63 disc (four slots and two for home) with a optical sensor. I wondering how my CAS looks like as you know I have an issue with the dwell that you are advising me already. Regards.

Greetings Adam, Thanks for the feedback. However it could be possible that the CAS has issues? I ask because this is a complete stock engine the only mod is the ECU swap and 430cc DW injectors. No cams or other big horsepower mods that this could happen (ignition scatter). Looking at the logs I don't see any trigger error issues which at first looks like there is no issues with the CAS and the ECU is getting a clean signal. The CAS that this car use (and Miatas) from the factory is the Mitsubishi 4G63 which is the same CAS that the Eclipse and other DSM cars use and also driven by the exhaust cam. I use the same factory CAS with other Mazdas that I had in the past with the same engine pushing 500+ whp without any single issue with other ECUs. Also I tune cars with the factory ignition pushing more that 300whp with the same CAS and again no issues. Now those car was running in sequential mode and the trigger was setup for 4G63. This car is batch firing injection because I am using the stock OEM GTX wiring. Which means I think the ECU does not need the home signal from the CAS for the calculations. The trigger pattern that my G4+ ECU setup is for MX5 which is the one that comes with the base map. I believe NB Miatas runs sequential injection. Based on that can you suggest if changing the trigger pattern in the ECU can resolve this issue? Please advise. Regards.

Greetings, I got the same engine, same distributor (dizzy) and same trigger discs. Stock OEM wiring harness. Here is my configuration for reference. Mazda 323 GTX Base Map attached (For G4+ PNP). G4+ PNP Mazda 323 GTX BP 1.8 engine. It should work right of way if you don't have problems with your wiring or CAS. Regards. Mazda 323 GTX G4+ Xtreme Plugin Base Map.pclr

Greetings, I am experimenting possible misfires issues with my car. It happens after the car is running after a while driving which means like when the engine bay is really hot. The car starts to misfires even at little load. I checked everything and is good in terms of fuel (pump and injectors which by the way are new from DW) base pressure looks good also. When I checked the last time the coil was burned (picture attached) which tells me that there is a problem with the dwell. The coil was brand new. I changed the coil with another one that I have spare and the car starts to work fine until I am starting to have the same issue again. The dwell time for this car (Mazda 323 GTX Turbo BP 1.8) is 3.5ms which is right. Because is a distributor as the rev increase the ECU should decrease the dwell but not much as this will create a weak spark and under boost is not good. But when I checked the logs I see spikes of dwell times of 3.8 and up which is not right. I think of the last burn coil and because now I am starting experimenting the same issue with the spare coil and what I am seeing in the logs with the dwell, I am pretty sure I have something wrong with the dwell configuration that could be frying the coil. For what I understand the ECU must not send more than 3.5 ms of dwell at any time. Logs and .pcl file attached. Please advise. Regards. Mazda 323 GTX Map Dwell.pclr Log 2020-05-23-10-59-45-am.llg

Thanks Dave for the feedback. Unfortunately I have to wait until next Monday so they can provide me with the correct code. Regards.

Greetings, I purchased a G4+ MX5Link Plug In for my Mazda 323 GTX. When I try to unlock the ECU with the supplied unlock code by the dealer, I got the following error (attached). I try to contact the dealer about this but unfortunately they are close until the next week. I just want to know if this error is because they provide me a wrong unlock code or something else. Please advise. Regards.
