Need help with Bipes
Hi all
My miata is currently n/a, I have a turbo and ancillaries to fit from a crash damaged car that I bought. I have taken the Bipes ACU from it already, and, using the instructions, I have fitted it so's I can get it working before the full turbo conversion. I have left off the CAS wires for now just so's I can use the settings to check that airflow and temp are working ok BUT it doesn't. When I set it to read airflow I'm getting all but one of the LED's lighting up, set to air temp, all light up. Set to revs, similar problem. I've checked and double checked the wiring and I assume the power side is fine as it lights up ok. Also double checked the switches on the rear are correct too. One question would be, do I need to wire in the CAS for it to take these readings or should this diagnostic side work without. I'm getting quite frustrated at the moment. Maybe I need to mention that it's a 1992 1.6. Cheers |
Update. Just put a multimeter on the airflow connection of the plug for the ACU and across to a suitable ground and when I rev the car the voltage drops showing that it works up to that point. I can only assume that there's a problem with the ACU. How the hell do I get THAT checked out?

Ha ha, it seems no one can help either side of the pond, oh well :(

I guess ill be the first to say it:
Step 1: Remove BIPES Step 2: Destroy so no human can ever use it ever again Step 3: replace with Megasquirt or Adaptronic Step 4: ??? Step 5: Profit |

There's certainly no harm in hooking it up to test whether this is the case. |

Step 5: Profit I WILL when I can afford to do so, I believe in the power of megasquirt but cannot afford to buy one and all the associated parts needed to get one set up properly. Or to pay someone to do it. Yet. I'll bear your advice in mind though when I can ;) |

This is just a guess, but since the ACU uses both RPM and airflow/MAP to calculate its operating parameters, its quite possible that the lack of a CAS signal is indeed preventing it from operating. There's certainly no harm in hooking it up to test whether this is the case. Hope you didn't suffer too bad a hangover from the drinking :) |
I love these guys. "I have the money for a turbo but i don't have the money for the right ecu." Or better yet. "My car is surging under boost HALP....No i dont have a wideband but i'll get one when i get money."
Do it right man. |

Sorry to say it how it is man. The consequence is blown motor. Can you afford that?
The engine is an assembly. Treat it as such. Basic setup doesnt exist. |

The engine is an assembly. Treat it as such. Basic setup doesnt exist. I'm asking as I'm interested, not to challenge your experience I hope you understand. The chances are that there are different experiences in the US from the UK, possibly from running a lot hotter in some states compared to this pissy windy country? Anyway, cheers for your time so far. |
Its not about running 20 degrees hotter air temp. Honestly Greedy shouldnt even be on the market. Matter of fact, spend some more time here and you'll quickly see people throwing Greedy kits in the trash soon after installation and installing quality parts.
What will quickly throw your engine in the toilet is running lean and not knowing it. I've seen too many blown motor threads because people are too excited to install a turbo kit instead of research how it works in the first place. Wideband is required even for a low power kit. Start with reading the faqs before installing your turbo kit and you'll be happier in the long run. |

Also check out the ebay thread. Good stuff that explains why partial kits are no good.

I am running a bipes and a begi fuel pressure boaster and seem to be doing ok.
What makes the Bipes trash? Based on the lights it takes timing out just fine. it takes out timing the hoter the air charge. It seems to take out timing fine as I apply throttle. Based on what the led lights are indicating it seems to take out timing when I want it to. I have no pinging or detenation that I can hear. Why is Bipes trash? |

I will change when i can afford it but the bipes seems to work for now. I just cant go over 8psi because my injectors will not suport it no matter how much I bump up the fuel pressure.
Timings is over safe if anything. |
Just to be clear i have had a miata for 30 days. If I am wrong or missing something let me know?
|
I dont see a wideband in your sig.

But the trash? Well, I'll admit that's where the FPR and oil lines from mine wound up, but the manifold and turbo are still perfectly serviceable six years later. Can you get bigger HP numbers and nicer-quality parts from elsewhere? Of course. I struggled to get 210 WHP out of mine, and that was pretty much the flow limit. But unless your name is Clarkson, it's a bit much to say that it's total garbage.
