Here is a pic of what I got in the mail today... V88 goodies
Time to get out of the dark age of EMS ( Microtech ) |
Maybe you guys can help me out with this..
What EGT,fuel pressure, oil pressure sensor should I get to work with the V88 ..? I will be using the factory TPS from my FD UIM and my Turbo II AIR temp sensor... Or I need to get new specific ones for this ECU? I also need a 4 bar map sensor, Can I used a generic one from AEM with the V88 ? Thanks in advance... |
No help :(...
I need to order the sensors... I guest I have to email Vi-pec.. |
Lots of good info, most of what you need, can be found here:

and PS,, throw the t2 air temp sender in the bin.. find something not using the ND curve . IE,, something faster action with a delco curve so you can pull the calibration file in easily

just a brief update:
i am close to being finished w the wire-in. i am enjoying the work. it does take time but the ViPEC manual is very well executed and combined w the Mazda Wiring Shop Manual, a few emails to ViPEC which were answered the same day, searches thru the ECU Section, and help from fellow board member, the amazing, Chris Ludwig i am comfortable as to quality of execution to date. there are lots of unique items. four type K thermocouples (two EGTs, one intake air temp and one turbo output temp sensor) two Bosch Mazda RX8 knock sensors new type engine coolant and oil temperature sensors new Link ViPEC four bar MAP sensor four IGN-1A ignition coils (each w 5 wires that had to be soldered into their fittings) four new custom Primary spark leads two additional Bosch EV14 fuel injectors, one pre turbo, one in the elbow two new EV14 1000 for my primaries a new wide band featuring the uprated LSU 4.9 sensor and Bosch chip three digital/logging pressure sensors, oil, fuel and AI system new Full Function Eng primary and secondary fuel rails new Full Function Eng Hall crank pickup system new turbo manifold, new CHRA for the BW turbo, new engine i am sure i am missing a few items but trail's end is in sight. today i should finish the engine compartment and monday i will move to the cockpit... mainly connecting a number of relays... fuel pump, ignition coils & AI pump. then there's dealing w the dash items... tach speedo etc it sure isn't over but it has been fun and will be exciting to experience initial blastoff. there are a few issues i need to solve, mainly the fan hookup and dash items. when finished i will post everything needed to do the wire in as i have been carefully making notes. i can't wait to get to the point where i can install my transposed maps from my Power FC and turn the key. howard He never specify a brand of sensor he uses for the coolant temp, Air temp sensor or fuel press only the map sensor.... I don't want to order sensor and stuff from NZ I want to get it locally here in the USA if possible.... I am also looking for a EGT and flexfuel sensor...... I email Titanmotosport and waiting for them to reply... |

delco curve is the resistance curve of the most common sender units
the information concerning this is readily avail .. the ECU must have the information about this so as to reproduce an accurate reading the FC air temp sender is a bastard.. it is a nippon denso unique curve and the best you will do for info is a very vague 3 plots and so your temperature reading in the ecu will be far from accurate the FD AIT sensor moved back to the common delco curve but is slow ( incidentally the FC and FD coolant senor has been delco curve all along ) the triumph part T1290510 is a much faster responding sender.. and uses the FD/ delco curve shape.. so you will have a better probe,, and infinitely more accurate calibration file |

If he cant help with your specific app, then he can def point you in the right direction. Although, I'm fairly sure he will be able to get you sorted out :icon_tup: Here he is on the forum if it helps too: RX7Club.com - View Profile: C. Ludwig |

I got a few questions answer by a Vi-Pec guru ( John Reed) ..... I am posting this for public knowledge..
Thanks John Reed for your time to answer all my questions about the V88... The V88 can used our OEM coolant temp sensor from a Turbo II and FD but not the AIT sensors... According to him is fine to used a GM AIT sensor and the 5 bar Map sensor from AEM ... Al pressure sensor from AEM or similar brands can be used with the V88 to monitor fuel and oil press and others... For EGT we need to get the RTD type sensor and not the K-Type ( the K-type needs a suitable amplifier to work) I hope this helps other.. Time to make my order.... |
glad you got it sorted

Most parts and sensor are in.. Only thing missing is the EGT dual channel kit.. Be here by the end of the week..
I hope we can get the wire harness started next week.. Some pics of all the goodies..... |
Nice. Hope it all gets sorted to your liking.
|
I am also thinking about getting this as a dash for the Vi-pec...

EGT kit is here..
|
Looks like a good setup your putting together.
Will be light years ahead of the microtech. |
I was talking to Simon fromViPec and found out that my V88 ECU needs to be send for a free Can upgrade.. This will allow me to integrate the Dash2 pro via CAN with the ViPec V88..
Hopefully I will have the Engine harness and sensors install ready in the car by the time the ECU get back from ViPec in New Zealand .. |

Finally all the parts are inn..
Racepak dash with ViPEC interface can cable.. I took the car on Sunday to Erick at Rotary Werks to start taking out the Microtech off the car.. Soon more updates.. Will be installing 2 1000cc injectors in the primaries injectors bank and moving the 2000cc to the secondaries injectors rail .. I will now have 8000cc in my secondaries fuel rail 😁 |
what turbo, what fuel?

I hate to see my car like this but work must go on...
|
Quick update... Been really busy at work..
The car start and idle beautifully all the sensor are reading and the timing is spot on with the hall sensor and EFF wheel... It has been a learning process for Erick ( Rotary Werks) and me... we have move forward slowly for safety reason... We still need to get some features working on the V88.. We currently have a EGT sensor reading 120 c more than the other.. We don't know why.. We put more fuel to that rotor and the car start to misfire ... It not fuel... Will be hitting the dyno next week if God permits... It been a long wait but I know I will be happy with the result.. |
try the individual rotor timing trim to retrieve the rotor temps .
though some difference is normal as no 2 probes sit identically within the same parts of the exhaust streams |
The car is home after 4 month....
We tune the car at 11 PSI in a different dyno came up with the same WHP at 11 psi.. At the same whp the car is totally different (driveability) behavior with the Vi-Pec compared to the microtech.... I love driving the car now with this setup... video and pictures update to come... I love the new racepack dash .... |
Good to hear you've had a better experience with this versus microwhack
|
Quick video of the Racepack in action with the Vi-Pec V88...

I forgot to thank Erick from Rotary Werks for all his hard work on the car.... His tune are great even in a new system ECU for him...
Now is my turn to help cleaning the engine bay :) |
The car is driving so smooth... Night and day to compare to my old ECU..
The only real problem is to learn all the options and put them to work..... It been hard for me to get my rotary tuner to really learn the ViPec ecu features .... I am currently looking for help online.. Maybe someone can remote tune and setup those parameters and finish my tune.. My main concern is to get my V88 to read my FJO correctly to set target AFR and fuel pressure drop fail safe also ... I email Neal @ apexspeedtech today, let see what he can do for me... |
Nice setup
What's the issue with the afr? |

What's the issue with the afr? I guess their is a calibration setup issue... |
Quick update .. Got a new wideband NGK with NTK sensor ... I think is much easier to get this one to work than my FJO with the ViPec and be on the safe side( this wideband is also recommended by ViPec)....
I like to thanks Dave from protuning from Australia (Pro Tuning Cairns) he has been very helpful answering all my question about my V88 and problem solving.... He also took the time to check my PCL file and make sure everything was setup correctly according to my wire install pin out of my V88.... He has giving more of his time and attention that most tuners that live here in the US... Will report back after the NGK wideband install... |
Why isn't the fjo reading correctly ?
If the afr to voltage settings are correct it should be fine proving it doesn't have a major ground offset issue between the wideband and the ecu. |
Took the fjo off the car and install ngk afx wideband ... Finally the vipec v88 reading the same as my ngk wideband.
More to come soon!! We are ready to start playing .. |
Wow what great day of tuning ...Finally got Dave from http://www.dtechmotorsport.com to remote tune my car.. Boy what a difference.. It feels 1000 time better.. I seen many tunes and tuner in my 15 years around cars and let me tell you Dave has some mad skills when it comes to the Vipec V88.. I watch him work around the Vipec software and do thing with it that blew my mind.. This ECU is great piece of hardware if you know how to work with it... This tune time today we used to setup everything little thing correctly in the Vipec software.. From target AFR to injectors dead time to trail and leading to coils dwell time.. He also setup some failsafe to protect the engine in case of fuel pressure drop and EGT events... The EV fuel map looks great... Next week we are going to finish the tune but before I need to get some information for Dave on my trigger wheel and connect my 4 port boost solenoid to the Vipec for better boost control and some more failsafe options... I will also like to thanks Eric from Rotary Werks for all his help and dyno time in his shop.. He has always been their for my car.. More to come.. I have a short video that I will upload when I get home..
|
Short video of today... More to come...... Falling in Love with my car...
|
Sounding good, wish there was a stateside Rotary / Link / ViPec Guru that did remote tunes ... that would be amazing.

Next week we will be road tuning if God permits.... Highway and normal street tuning! We are moving forward... |
Good to hear you got it all sorted.

Little Update from the Dyno: we took the car to 16 PSI and made 407 whp and 320 tq.. Dyno sheet to come Eric had to go home for anniversary... Remember my stock GSL-SE differential don't like power...
I am in love with this 30 year old car :)... More to come from the Dyno next week.. We are setting up the knock sensor.. I had RX8 knock sensor but my tuner recommend some bosh unit that I will install next week.. I can finally run any ethanol content from E10 to E85.... We also play with the Ethanol temperature 4D tables.. We are also controlling the boost via the vipec and added safety with over boost and other features with the boost valve.. All my sensor are working and earnings their pay... I also receive today something that I think is very important in our cars... Safety first.. Jose |

I been extremely busy the last few weeks with work ... The knock sensor are install and my Christmas gift came in early this year.. Now I can have AFR on each rotor pre turbo for more accurate tuning.. I love data..... Let see how it goes..
|
thinks that having AFR measurement pre turbo is a no no.. for probe life, but i think also the backpressure skews results
( becuase the wideband is always comparing the sample to "free air " found from inside the wiring pigtail and having high backpressure at the sample point excludes the reference sample of 'free' air ) much better to have individual exhaust temp senders each runner and a single wideband after the turbo to best gauge individual rotor tunes PS aem sell a "exhaust backpressure " kit 30-2064 which is intended to match with the 4 channel UEGO to allow you to compensate the readings taken pre turbo |

UPDATES...
Finally got the car on the dyno for a break in tune.. many changes on the car...( new Rotary Werks exhaust manifold with twins precision wastegate, Pre Turbo wide band and Semi peripheral high compression rotors.) Dave form Dtech motorsports from New Zealand did a great job setting the new sensors and tuning the beast .. The car feel's great ... Now is up to me to get some miles before we do the high boost tune... The Semi Peripheral is great and the turbo comes alive quick compare to the street port only.. |

Screen shot of the remote tune on Friday... Dave from Dtech Motorsport really know his ViPec ECU... You can see in the picture all the sensors working in harmony, specially in the log files ....
